INFOTABLE Properties - why can I sometimes not delete rows?
Sometimes, with an infotable property, when I am editing its values manually in Composer, I cannot delete rows, as in there is no option to select a row to use the delete button with.
I used to think that this was due to the table's datashape not having a primary key, but that is not the case as I just proved to myself.
Is this a Composer bug? Or am I missing something? Here is an example of a Thing with a property Versions using a datashape that has a primary key.
