xNt write errors (not enough space)

NXP app gives not enough space when trying to write less than 880 bytes. (Even as few as 64b)

I protected with DT app as soon as I got home from piercer.

Successfully wrote phone number to chip, now getting these size errors

Is this on an android?
Have you tried NCF Tools?

Looks like it was just a bad app, NFC Tools seems like its working well so far. thanks!
