Thank you for your post.
I am unable to replicate the issue using FileMaker Pro Advanced 16.0.2 under Windows 10 Pro. Can you update to 16.0.2 and see if the issue still occurs?
It still happens with Advanced 16.0.2 ... but it seems only for hosted files. I will do an update from FMS15 to FMS16 and let you know if it still occurs.
We just update to FMS16 and compressed the file - now everything works as expected.
Thanks and best regards
