Only thing I can think of that could help is to try installing 1.8.5 on a new card and then use the BBM to export your project to the card. Test it on the pedal. If this solves the issue, install 2.7. Don’t get in a hurry with the process. Oh, don’t forget to reset your pedal settings. As this is a long shot suggestion, please let us know if this works.
Here’s a link to f/w 1.8.5 Firmware 1.8.5
