How are these computers connecting to the mailserver?  If it's IMAP, the
client and server will resync when the client connects ... so if your
oldPC last sync'd a month ago, it'll take it a while to validate what
it's supposed to do with the (now deleted) messages that it still sees
as 'new' since the last time you sync'd.

Note that some mail clients don't always play nice with the IMAP updates
(I'm lookin' at you K9 Mail), so they leave messages "unread" even
though they've been read on another device.

If it's POP ... there could be other things going on, since it's pretty
much designed to only pull new messages.

Sounds like kmail may not be configured to tell the server to delete the
mails when you've deleted them from within the program (or, it only
sends the purge command on user request).  This means you delete them
from the kmail view, but when mutt queries the server, they're still
