Sadly the first bug that I mentioned is probably rare because when I tried to trigger it it didn't happen again, so what happened the first time was when I chose the wrong choice and I wanted to rollback so I pressed the back button and suddenly the bug happened and like I said sadly it didn't happen again when I tried it the second time
The second problem as you see in the image one of the choices was outside of my screen, here my phone screen spec
Size: 6.3 inches, 97.4 cm2 (~83.6% screen-to-body ratio)
Resolution: 1080 x 2340 pixels, 19.5:9 ratio (~409 ppi density)
I never encountered this problem in other vn games that I've played
