Thank you for your post!
I was unable to reproduce this behavior with FileMaker Pro 16.0.1 (Advanced) on MacOS Sierra 10.12.3 or Windows 7 Professional (64-bit). To attempt to reproduce I followed these steps:
1. Created test.fmp12
2. Imported 50 records of sample data
*Repeated following Steps both locally and hosted on FileMaker Server 16.0.1
3. Entered Form View
4. Modify Record
5. Command/Ctrl + T
*Repeat 4. and 5. until the found set is 0
Are you able to reproduce in a New File?
Do you have further information I might need to reproduce?
I did so and found no problem. I also went back to the file I mentioned had the problem and today no problem. I think it was a one-off issue. Thank you for helping. - Brian
