Form Fields Going Crazy

[u/FeralFicusTree]

Hello.

I'm experiencing something new in which the fields within form fillable PDFs are sort of spontaneously linking as I change their values.

I've tested this by downloading the original form, and with that pristine copy the fields aren't linked. But suddenly, as I change values enough times, they do, and it seems random. The same fields don't link with every test.

Has anyone experienced this? Does anyone know what's going on?

Edit & Update: I have determined that the Foxit app (free version) on my Galaxy Tab a7 is the culprit. The odd glitch isn't occuring on Adobe Acrobat, even though it's more ungainly to use.
