Impossible to save and use new profile

Hi

using Shutter 0.94.3 Rev.1306

on 20.04.1 LTS (Focal Fossa) 64-bit
Kernel Linux 5.4.0-48-generic x86_64
MATE 1.24.0

after the restaert of the applicaion I'm not able to reuse any profile added

- Edit -> Preferences
- Changes directory or other settings
- Click save icon
- Prompt appears for "new profile name"
- Save
- Usage: it works normally during that session; I can switch between them.
- After the restart of the application the new added profiles are not available anymore; only the default one.

thank you
Mik
