Hi @yojimbo274064400
First of all thank you for the comprehensive response.
Followed your steps and pasted the results below.
Corporate:
[PERMANENTFLAGS (\Answered \Flagged \Draft \Deleted \Seen $Forwarded $MailFlagBit2 $NotPhishing $Phishing $label1 $label2 $label3 $label4 $label5 $labelvivCoupons $labelvivDelayed $labelvivDone $labelvivImportant $labelvivImportanteTorres $labelvivJunk $labelvivKeptBack $labelvivMilestone $labelvivNuances $labelvivToFollow $labelvivToReply $labelvivTodo $labelvivVBSolved "\\*")]
Personal:
[PERMANENTFLAGS (\Answered \Flagged \Draft \Deleted \Seen $Forwarded $Junk $Label1 $Label3 $Label4 $Label7 $NotJunk $NotPhishing $Phishing $label2 $label5 $labelvivCoupons $labelvivImportant $labelvivImportantPessoal $labelvivToFollow $labelvivToReply $labelvivTodo $labelvivVBSolved $labelvivVBs $labelvivirs $labelvivrevoked teste "\\*")]
But even if the problem is in the collation the end result is the same.
In steps:
I remove the only personal message I have labeled as Important and remove the duplicate entry from labels;
According to the previous step and vivaldi's UI I now have only corporate messages labeled as Important on the default label ($label1);
Then I label one personal message as Important using the only label visible in vivaldi's UI (should be a default $label1);
What I see with the previous step is now a second Important label with the message while the one that existed and was used from to UI to label the message does not show it.
I can do more. I can then add the other existing important label to the message with this end result:
4d800819-2f9f-4d40-aa77-d15128bf4f58-image.png
In this case removing any of the labels removes the other.
And at the moment it appears I bugged out vivaldi since on the message list I have:
c59d6c02-8c47-42e2-aec3-8cd0ea4e8f0b-image.png
And on the message headers I have:
5aecfbac-2c14-4aa7-ac6b-0e0d0e778d46-image.png
So something strange is happening here.
P.S. The bugged out behavior got corrected on vivaldi's restart but the rest of the behavior remains.
