I think this sort of thing is an interaction between Evolution and the
IMAP server.  Sorry if this is going over things that you already know:
the historic IMAP default for deleting things is to mark the message as
deleted and then sometime in the future purge the deleted messages;
this is how Evo still handles deleting messages internally. Many IMAP
providers now don't particularly play well with this paradigm and by
default use a Trash folder of some form and Evo will also now do that,
but it implements it by copying the deleted message to the Trash, then
marking the message as deleted in the Inbox (or wherever); those marked
messages are usually then purged immediately(ish) by the server or
purged by Evo when changing folders. I use iCloud mail and it takes
about 4 or 5 seconds for the deleted messages to actually disappear.

So, for your particular issue, it may be that the IMAP provider has
changed it's frequency of removing marked messages; it may also be that
in the past you were not seeing the marked messages and that may have
been accidentally changed (View -> Show Deleted Messages).

I think that is the case. If the deleted messages aren't visible, it
won't select them!
