Once I enable a local major-mode.  After some time I decided to remove it.  So I deleted it from disk as well as from configuration (<kbd>SPC</kbd> <kbd>f</kbd> <kbd>e</kbd> <kbd>d</kbd>).   But it is still available in my Spacemacs.  At least I see all its functions in <kbd>M</kbd> <kbd>:</kbd>.

How I can remove it completely ? Is there sort of "compiled cache"?

I'm not even sure that this is just the eval history.  Because I can call these functions/vars and see the result of their work.  As if i didn't remove the major mode at all.  Of course, I restarted my Spacemacs many times (<kbd>SPC</kbd> <kbd>f</kbd> <kbd>e</kbd> <kbd>R</kbd>).
