26C Learning Catalog Adding Columns

Summary:

When we load up the Learning Catalog, we are having various inconsistent errors.

Content (please ensure you mask any confidential information):

If we load up Learning Catalog and filter it to events and then add the column 'event start date' and 'event end date', it won't populate the columns (shown below). We then have to exit Learning Catalog and go back in. This then appears to resolve it.

Sometimes not all the column options appear and it has a loading bar. We can only make this disappear, by exiting Learning Catalog and going back in.

Is anyone else experiencing this? Is this a known issue?
