Random functions showing up in my script editor

About 10-20% of the time when I edit a script there's an error. If I scroll to the top there's a function that's been entered at the top that I didn't enter (see screenshot below). It's often something early alphabetically (i.e. a function starting with an "a". I feel like this might be a function of a MBS plugin, or something else I turned on that's auto completing.

Any thoughts? Is there something I can turn off? Do other people experience this with or without plugins?

I wonder if in editing the cursor went up and you typed maybe a and FileMaker auto completed it?

That makes sense, but it happens so often and is super frustrating. Do you think that's related to MBS, and if so what should I turn off to mitigate that?
