I have created a simple question linked to a MongoDB collection, in which I just do a simple count of rows grouped by a field "serviceName". That field can have different kind of values, sometimes it's a simple string, sometimes it's a URL beginning with a slash.
When I add the question to a dashboard, and add a filter linked to the field "serviceName", all values beginning by a slash are not shown in the filter choices, and can therefore not be selected.
Is this a known bug ? (didn't find anything about that so far).
I'm using Metabase v1.49.13.
