Duplicate Fields in Filter Search

Question

Problem: 
When searching under the filters tab in Jira using JQL the fields appear twice.

This does not happen when using the Basic search or when searching within any Jira Service Management or Work Management project.

When you attempt to select one of the field options it may or may not select the field. Ex. If you select the first "Customer ID" field it will select it. However, if you select the second "Customer ID" listed it will instead show "Customer Name [Dropdown]" ensuring the second option can not be selected.

Troubleshooting so far: 
I have looked under admin > Custom Fields and have not found any double fields.

Looking at all other search options besides filters(searching within a project, creating a queue in a project, etc.), I notice that this does not appear to be a problem

I was thinking this may be the case because we have team and company managed projects. 
However, the user who originally flagged this problem told me they had not seen it before today but no new projects have been created lately or had permission updates and I was able to replicate the problem. 
The other concerning problem is not being able to select the second instance of the field to figure out which projects that this might be associated with.

Thank you so much for the information! I was feeling crazy - glad it's not just me. I'll keep an eye on the status updates.

I don't believe the active incident is the cause here but certainly could be wrong.
