hierarchy property is missing in entity dimesion bpc 7.5 nw

we are working with bpc 7.5 nw version and had some problems during the installation process. now our system seems to work but we still have some issues regarding some default dimension properties.

In our entity dimesion and P_CC dimension there is no hierarchy property (parenth1 and so on) while our account dimesion has this property. and as we tried to add this property we get an error message.

how can this problem be resolved?

best regards
