Warning Fillet is missing (x) edges when trying to edit feature

Why do I get a warning message when trying to edit an existing fillet feature?  The part file is attached, as is a screenshot showing the error message, just in case this is a software hiccup. As you can see on opening the part file, the fillets are there.  Try to edit either fillet feature, they go away and the warning pops up. I can go into the property manager and remake and accept the fillet feature, but if I try to follow up with another edit, the selected edges are removed and the same warning pops up.
