alerts for quant model changes not working

Avatar

The alert correctly works when my price threshold gets triggered. However, when the quant model updates the alert does not trigger. 

e.g. I had an alert for "hold or better" on JMIA. JMIS switched to HOLD from SELL a few days ago, but the alert is still set, does not show that it's been triggered, and I received no notification. This is just an example, I've seen this now multiple times when I manually review tickers.
