Omnichannel routing set up error

I am attempting to set up omnichannel routing ahead of implementing skill-based routing for our team. I continue to run into an error preventing this. A screenshot of the error is HERE, and a screenshot of the current tag set up is HERE.

It looks like the platform thinks we still have chat live, although this was deactivated and we migrated to Messaging quite awhile ago. I've dug through every resources I can find to ensure chat is fully desctivated.

I have followed every instruction and troubleshooting guideline I can find within Zendesk resources and have hit a brick wall. I have also reached out to Zendesk help multiple times with no response. This is becoming a significant issue, as we need skill-based routing to be implemented and working well before year-end. 

Does anyone have any ideas??
