New product categories hidden for 'storeadmin'

[Engholm]

Hi,

I figured out a problem with VM User Group 'storeadmin'. Everything works fine. Storeadmin kann create, edit and delete products and manufactures. Exept of 'product categories'. A new product category can be added by a storeadmin will be saved without an error message but afterwards the new category hidden to group storeadmin. Only Superadmins kann see the new category.

Settings:

Admin => Superadministrator
Storeadmin => Administrator (everything around VM is set to allowed in ACL and has been calculated as Superadmin) => assigned to the same vendor as Admin

Standard language german. No multilanguage store. Store is set as catalog.

J2.5.14 / VM 2.0.22c and 2.0.22d

Could it be a bug or have I missed something?
