We've just set up CRM and we completed a data import from Hubspot. In cleaning up the relevant contact fields, I came across a "Status" field (Single Line). This doesn't seem to be a default field (not in the list on the knowledgebase) but it also isn't a custom field (description text is in solid black), and when I hover over "Remove field" the popup says: "fields created through plugin will not get deleted". I'm not sure which plugin this relates to.

I can't seem to hide / delete it, but I don't know what it's from or what to use it for. 

Any help would be appreciated!
