Block Navigation Panel duplicate object listings

This morning I noticed that there are redundant object listing in the component list on the block screen (see image below). It SEEMS like it might be related to some sort of change with alerts, since Alert1 appears multiple times AND my app has multiple alert objects. Interestingly, none of those alert objects are names “Alert1”

Is anyone else having this issue or is it just me (windows 10 chrome)
