Upload - Sync Error - Bad Request after update

After the last update, I have a calendar item that throws errors.
eM Client version 10.0.530
I believe this is because the email account does not have calendar support. (I have two accounts one is email only, the other has both)

Error Header: Synchronization of folder myemailaddress
Error: Failed to upload item “descriptive text of the event”
You may choose to detect the item locally or ignore the error. If you decide to ignore the error now, item upload will be attempted during the next synchronization.
The server returned the following error: Bad Request
The target folder was [email protected]/myemailaddress

*** No matter what option - delete or ignore the same item fails to upload, and the error returns.

I have not found this exact issue, and I am wondering how to clear the item manually.

You can choose the Ignore option, then open the event and save it in another calendar’s folder.

To clear any other pending uploads, right-click on the folder and choose Properties > Repair > Repair.

Thanks so much for the reply.

I attempted this, but the item will not be deleted. It is now strobing on and off of the specific account calendar. I see it in the correct account, but the “broken” one is still an issue. Tried deleting it (all occurrences) but comes back.
