Last night some shortcuts such as Move to Folder, Archive, Delete, Mark as spam, and others, disappeared from my Mail menu bar, along with items in the vertical three dots extension such as Mark as read, Flag as, Mark as unread, etc.

What I now have instead are Filter, View archived, Attachment options and Sort by, while the three dots menu extension now contains just Turn on conversation in this folder.

I thought at the time it was just a Zoho glitch, or it would be Ok after rebooting this morning, but it is still the same. Please help me get it back to what it should be urgently!
