How do i stop the fill & sign tool from auto switching from text to check mark?

Im using Adobe fill and sign tool to fill in information manually on a pdf form that was originally created using FormConnect ( A .FMC file. App only available for apple so i can't use that app so i have it converted to .pdf so i can somewhat edit/ read what the forms are.  I so wish Android had a app similar to FormConnect.  Unfortunately either due to the file formats or perhaps just my own ignorance, the Work is tedious. Thankfully it isn't much on the form that's so tedious but still enough to be very annoying. When switching from spot to spot in fill and sign mode,  adobe will randomly auto switch from the add text mode to a add checkmark mode.  Which i then have to delete and switch back.  This appears to only happen when the box im clicking onto is a smaller box,  and never on the larger ones or empty space.  Ive included a screen recording to show what i mean.  My device is a samsung s23 ultra. Please tell me how to stop this. Or better yet,  a better way go do this stuff or even better, a way to open and use .FMC files on android!
