That sounds like a nonconformance to me.

I would absolutely manage it and record it as per procedure - in which presume you mention this tool as a kind of infrastructure?
I usually see an NCR system used for 1st, 2d and 3rd party audit nonconformities; some people use the same system for Opportunities for Improvement that they decide to treat as preventive actions. The NCR systems are sometimes also used for customer complaints, and why not?
What I often don't see is the tool's functional capabilities leveraged as a mini project management tool for things the system members find they want to improve internally, that is without the trigger of being a finding of some kind. That is understandable if the system makes it awkward to sort out such actions for reporting purposes, but it still seems unfortunate, a missed opportunity.
