That screenshot appears to be from the Android version. Did you make the same selections on the iPad? I just tested this on my iPad Pro, and I had no issues adjusting the fixed duration, and it was still set properly after force closing MobileSheets and starting it back up. However, the iPad version appears to be only accepting whole integers, so that's something I'm going to have to investigate. So don't try to enter fractional values in the iPad version at the moment, as it looks like the fractional part may be stripped out.

UPDATE:

It looks like just an issue with how the value is displayed. The fractional amount entered is correctly saved and used. This is fixed for 3.9.0.
