Hello, can anyone help me?

For a while I have this issue when I try to click on a suggested word to autofill a form.

In example, to make it more clear what I'm referring to: if I try to login in into something as Giniroryu, I type G and it brings up Giniroryu suggestion, but I cannot click on it to fill the form without continuing typing. I can from the keyboard, but not from the popup on the app itself.

I use Chrome and Brave and happens in both. Tried to look for some kind of option that might be inactive but to no avail. It doesn't seem to be a screen problem, works fine for anything else and I calibrated it. Anyone has any ideas?
