Big Problem with Depend Step

Hello there,
i just checked random some settings and i also check the Product Builders > Products > Depend Settings, then i realized, that one Attribute won’t show for some reason. I know and i am 100% sure that this was working, in the first Step i added the Depending On Product and under attributes i just added 2 different Attributes. But now for some reason, the second Attribute wont show anymore!

I dont know what to do! The second attribute shows from step two. I dont get it! It was working 100% and i tested everything, it was perfect. But not because one attribute is missed, the Configurator dont work correctly.

in the next reply i will send more details and images…
