Untrim not working

Hi,

I have an object with letters trimmed on a patch. I have selected all the edge curves and hit delete. Most of the text is now gone, and the untrim has work.
But 2 elements are impossible to delete. whatever i do they can't be deleted.



How would proceed in this scenario to do an untrim ?

Thanks for your time.
Cheers
E
