Queue Item is deactivated when an email is routed to a queue

I am using CRM online 2016, no email router, I have an automated creation and update rule set up to create cases from incoming new emails but I still want to be able to create a queue items for emails related to existing cases (so not create a new case), however it seems that queue items are deactivated for all incoming emails, when I deactivate the update rule queue item all works fine and QI is a not deactivated. 

this doesn't seem right to me, does anyone know how to stop from queue item being deactivated?

thanks,

Martyna
