Try swapping your rings around. (front to back, back to front) See if this helps. Also, flip rings around (front side turned around backwards, backside to front side). Make sure your scope is centered over the bore.

This is what I use to square up my scopes.https://www.brownells.com/gunsmith-tools-supplies/sight-scope-installation-tools/scope-reticle-levelers/vertical-reticle-instrument-prod6097.aspx?psize=96
First, you square up the mounts. Then the scope so that everything is aligned with the bore.
Today I noticed when my scopes are zeroed at 25 yards they shoot low and left in the basement at 10 yards. When i zero at 10 yards in the basement I'm high and right at 25 yards. I'm using Hawke match mounts and sports match dovetail mounts. I use these because they have recoil pins and hang tight to my springers. I expected vertical differences at these ranges, but it's annoying to have to change windage adjustments all the time. I like the idea of the self centering BKL mounts but they don't have recoil pins and don't want the scopes sliding in the dovetails. Is there a solution to this??

I used to have a laterally shifting poi "close to far" till I simply leveled the R9 or HW95 using a "tested good level" on the barrel pivot "flat spot", then rotating the scope in the rings till the vertical crosshair lined up perfectly with a hanging string with weight, the verifying that both the "level bubble" was centered and the reticle was aligned with the hanging string.......Anywhoo, I shot this "trajectory target" to get a handle on the trajectory of a certain tune level using the above scope alignment method coupled with optically centering the scope via "mirror method" and then bending the barrel till the poi was 1" (or less) of the poa, then the fine adjustments were done using the scope turrets. As usual, all 165 shots were taken sitting on a bucket resting the gun on cross sticks............As you can see......all groups were vertically aligned from 10 yards till the first 45 yard group, however I decided to tighten the barrel pivot bolt a tad since the barrel pivot tension had gotten "sloppier than usual" after thousands of shots. The second 45 yard group and the barrel pivot adjustment shifted the poi about 1" to the right. Readjusted the windage and shot the last two groups at 50 yards. Anywhoo....for my HW break barrel springers optically centering the scope, bending the barrel till the poi matched the poa, leveling the guns with level on top of barrel pivot block, then rotating the scope in the rings till aligned with hanging string before tightening the mount top straps has worked for me.
I was considering the UTG rail adapter you're using but it mounts the scope higher than I like. It works and looks fine on your guns with 50mm objectives. With my 40mm objectives it just won't look right to me.
According to BKL, base mount screw 35in/lbs. Scope rings torqued to 15in/lbs. It's important to have a properly working torque wrench.They also make a point to say: "Do not close the gap between the edges of the ring (the flat surfaces where the screws are) as this might crush your scope tube! Please refer to our technical data sheet for more information."https://www.bkltech.com/articles.asp?id=134
