This has been an issue for as long as I can remember, but I always forget to create a ticket for it. Not sure if this is the same issue as #39, but it also happens in Doom with the pinned iedit version.

When accepting a company completion while multiple evil-multiedit regions are active, the prefix that was used to trigger the company completion doesn't seem to get committed to the other regions while the completed part does. See below for a demonstration where lsp-mode's capf backend completes bar for me after I typed a b. When the document automatically reformats on save through lsp-format-buffer, only the ar part remains.

On a side note, is pasting on a visual selection being broken in evil-multiedit (with Doom) also a known issue? When I use viw p to replace the selected word, only the actual word I'm editing will contain the pasted text. The other regions will be empty.
