Comment keybindings not working properly in MyEclipse, possibly due to CodeMix

Question

Up until a few days ago my My Eclipse 2017 keybindings for toggling comments in typescript and JavaScript was control-slash and control-shift-slash and control-shift-backslash for block comments in html.

However, now the only binding I've found that works is control-alt-slash which only adds html-style comments in both typescript and JavaScript and html. The keybinding does not toggle comments out and control-alt-backslash does nothing.

I did two things that may have caused this:

I installed CodeMix on MyEclipse. However, I uninstalled all CodeMix extensions and the problem still occurs.

I changed the name of my MyEclipse workspace, which caused MyEclipse to create a new empty workspace with the old name. I tried pointing MyEclipse to the newly renamed workspace but that caused filepath errors so I just changed the name back and deleted the empty workspace. I'm worried some of the workspace preferences got changed during this process and is causing my problem.

I've tried changing the keybindings but nothing seems to work. I've included some screenshots of the keybinding screens and the results of using control-alt-slash in typescript.

According to this thread Genuitec is aware of the problem and is working on fixing it, but I can't find any updates on the problem since the last post in the thread at the end of February 2018.

Any help would be great! I might try reinstalling MyEclipse but I'd really rather not...

Thanks
