Odd / unexpected filter behavior

Can anyone explain how the following might occur?
I’ve set a filter for the following :

And then the result is this :

I don’t understand why the last entry is shown - since the editing box is NOT checked.

I do wonder if it relates to my previous question here : https://community.coda.io/t/setting-a-lookup-column-via-an-action-button/13555/2

Because if that is indeed working behind the scenes, then this row WOULD have editing checked. Its extremely confusing to me. But like all these things, its also probably straight forward and I’m looking the wrong way…

EDIT : Even more interesting…

Once I’ve filled in the Stage column for all 3 in this view, all 3 of those are able to be selected from in another table (filtering by the workflow name)

So - from this…

I get the following selection in another table

This really has me stumped!
