Attributes not displaying

Good Morning.

I have an issue with the plugin where some attributes are not displaying on the list of attributes for the “Depend” panel of the builder (See attached images)

In my case, i created an attribute called “Socket (Builder)” present on both motherboard and CPU categories. but i’m unable to select it in the Depend panel for the “Processor” step but i can find it in the memory step.

Please can i know why ?

Thank you.
