Forms with CrocoBlock - Jet Engine

I have an update user form connected to a bunch of user meta fields set up with Jet Engine. Having a few issues with the checkbox fields mainly and also a dropdown.
The fields are all set up using Manuel Input in Jet Engine as I found out the hard/long way that Fluent Forms does not work with glossaries items currently. Glossaries input setup was the reason I was told that it was not working originally.
But still getting issues.

I have 3 issues or bugs that Im finding.

1) Ive now made them all manual input and Im still having issues where the checkbox fields only seem to be going one way. What I mean by this is that, I can select an checkbox item, and I can see this on the user meta as selected. The issue is, if I uncheck the checkbox then it will not update on the front end showing the default selection.

2) The other issue is, if I make the checkboxes have Conditional Logic then the form completly errors out with:
There has been a critical error on this website. (this was the glossaries issue)

3) With a dropdown, if I select the "enable Searchable Smart Options" (If you enable this then options will be searchable by select2 js library) then the default selection does not show. If I turn this off then you can see your selection fine, but just not with it turned on.
