PSPAD entry has disappeared from the context menu

With version 5.0.1, I had 3 entry in context menu :
- PSPad
- PSPad HEX
- PSPad Diff
After update to 5.0.2, I have only :
- PSPad HEX
- PSPad Textdiff

After to switch with DLL and Register option, the 3 entry has reapperared.

Strange ...

DLL is better solution than registry.
And I agree, it's strange. But easily to fix - uncheck in program settings / Integration, apply, check and apply again.
