Value not passing from a form on iPhone

I have a form that’s sending data from a couple different User Profile Columns. If I submit the form through the Glide builder interface, all data passes normally to the sheet as well as the data editor. If I submit the same form from my iPhone, one of the User Profile Columns won’t send its data. All other columns send just fine. The only one that doesn’t is a column using Single Value. I tried that column both with Random (my preferred method) and First. Can’t get it to send that data from my iPhone. I’ve also tried restarting my phone.
