Apple watch touch is partly not working?

Hello there!
I need a little bit help with digitizer replacement on apple watch SE.

Here is the problem: I did manage to do few successful glass/digitizer replacement, but recently one problem started to appear, the right bottom corrner of display doesnt react to touch. Even if i check the digitizer before instalation, it happends again, and so far happened about 5 times in row.

Im using the LOCA technique as i dont own autoclave.

Im trying to figure out what is the part im messing up, as most likely its my foult, tho few digitizers i bought didnt work properly.

Maybe its worth mentioning that sometimes if a little bubbles appear on LOCA during application i squize them out using very little of pressure around the spot, but i dont think thats the reason for malfunction.

Im kindly asking for any advice!
