Apple Pay not working after screen replacement SE/SE2/5

Hello everyone
After i replace the screen of various watches for another original screens the apple pay stops working.
it shows an error when trying to add a new card.
I know models 1/2/3/4 had this problem, because the nfc chip was on the back of the screen, but I never had this prolem with models SE/SE2/5 and up.

If I put the original screen back on the watch it works perfectly.
The screens I'm using work perfectly. If I put them back on the its original watches everything works perfectly.

Does anyone know what is going on, and how can I fix this?

Thank you for your time
