Fillable form won't let me type unless I right-click then tab through

Hello,

I have a fillable form that has recently stopped letting me click on the field and let me type into it. 

I have a picture attached for reference. 

It will let me click into the field and then another blue box will pop up along with a rectangle that, when you mouse over it, it has the "fill in form fields" symbol to the left and "request e-signatures" to the right. 

It already shows the "fill in form fields" symbol as being greyed out, as if I can already type into the field however, not even a cursor shows up when trying to click repeatedly in the field. 

I have found that, if I right-click in the field, it will then show the cursor with just the original field, no secondary field inside of it, and will let me type into it. 

I have checked security settings and also e-signature settings and everything looks good. 

To be clear, I am NOT looking to have e-signatures anywhere on the form and it is NOT setup for them either. 

Any help would be greatly appreciated!
