I created a number of indexes using Python's pymongo module. I check the MDB CLI to see the indexes:

However, when I try to visualize the data in MDB Compass and click on the "Indexes" tab, it says that my namespace does not exist:

You can also see that the collection information on the top right are all "N/A". 

I tried refreshing the database by click the top left refresh button. That didn't work.

The thing that did work was opening the collection in a new tab. Only then did it refresh and list my indexes and show the right collection metadata.
