v15 List Manager

Hi, all-

Does anyone know if there is a limit as to how many selections can be added to a field in list manager?

We have a field and are trying to select 16 options, however we are unable to save and close when we hit 16.

We are fine with 15.

I didn't see this in any documentation so was wondering if I either missed it somewhere, or if others are experiencing this as well.

Thank you!

Rachel
