Duplicating draft emails

eMClient 9.2.1735 on Win11 Pro i5 machine.
When I create a new (draft) email I get multiple copies both in the Drafts and Trash folders. It seems that every edit creates a further duplicated copy. It’s a GMail account and this is not replicated in the Gmail web-based app.
I’ve just created a new email and there are 13 copies in both Drafts and Trash.
This started around 3 months ago and is not consistent.
Anyone have any thoughts on this?
Thanks.
