Issue with Opus Email Dialog

I'm having an issue with the Opus Email dialog.
When selecting email recipients and TABBING away from the TO,CC,BCC fields Opus now automatically places a slash at the end of the chosen email address '' which invalidates the address.
I've been using this feature for years and I noticed this issue a while ago but I've been to busy to post.

Also what is the delimit character for these fields (TO,CC,BCC).

Thanks for reporting this. It has been fixed for the next update (12.7.1 and 12.8).
