How make copyq clipboard manager ignore keepassxc passwords?

Hi

I'm running:

• Mint19
• copyq v4.1.0~bionic
• keepassxc 2.6.6

I'm trying to make copyq ignore clipboard passwords copied from keepassxc.
I've followed this link and this link.

It "sorta" works where copyq will ignore the first clipboard password. If I keep copying "different" passwords to the clipboard, they are successfully ignored. But as soon as I copy the same password twice in a row, that password shows up in copyq.

Would anyone know a fix for this?

Thanks
