strange pattrstorage issue

Hey,
I have a 'write globalPreset.json' message connected to a pattrstorage. When i remove the json file out of my patcher-folder and i remove it anywhere else (in the dustbin, anywhere in other folders), he doesn't write a new 'globalPreset.json' file. Whenever i give the write-message box another name, e.x.: 'globalPreset1.json' it works perfectly and a new 'globalPreset1.json' file is saved in the folder...i don't know what the problem is. Why doesn't he take 'globalPreset.json' anymore although i removed it everywhere? It's really only with this 1 name 'globalPreset'.
Thanx for helping
Cheers
