New Livery Not Working

Hi captains, quick question: I,m creating liveries for the GndHandling, so far i created 3, 2 of them are loading fine but the third one is not loading in X-Plane (tried in many airports).
When i choose this livery (3rd one), X-Plane brings the default livery for GND, anyone got similar issue before?

Note: i compared the photos of the 3 liveries (size, dimensions, pixels, etc.) and they are all the same. And i created all of them from the same paintkit in Photoshop.

Please advise.
Thanks in advance.
