Hello, I've started down the Unlocked Packaging trail and have built a couple of packages for some of our Orgs. In one of those packages I have a fieldset on a custom object that is used in a SOQL to return data with a custom. After installing the package in another scratch org and adding an additional field to the object I am not able to add that field to the fieldset through the UI. I can remove the existing field but no other fields show to be added. I can however add them through metadata in the dx project. Anybody run across this. I'm working on some sample code for this but thought I'd ask the question here. 

Thanks in Advance,

Dave Casper
