Command Manager Sketch Tab Disappeared

Hi,

I'm using the Solidworks 2018 SP3 Student Engineering Kit (SEK) and there's no sketch tab available in the command manager

And I can't enable it in this right click menu.

A bit of background:

I was using the student design kit (SDK) fine, then got a license for the SEK and upgraded it, then I lost the sketch tab.

So I've tried to run in safe mode from Solidworks RX; repair the install; reinstall it; and also deleted the registry to reload it.

None of these worked.

Any ideas?

Thanks in advance
