Thank you for pointing that out. You’re correct; the toolbar at the bottom is actually added by the MAKE.md plugin. After some trial and error, I was able to resolve the issue by disabling and then re-enabling the MAKE.md plugin. I’m not entirely sure why this worked, but it did!
I’ve also checked the settings and the forum thread, but neither provided a straightforward solution until I tried the disable/enable trick.
Thanks for your input! It’s much appreciated.
