Issues with accessing data for filtering from related collections

[majid]

I am trying to filter from 2 connected collections ‘voucher item’ and ‘voucher category’ using a Dropdown menu for voucher category and Card list for voucher item.

whenever I try to get the voucher category name to filter on the Card list I can’t seem to find it. as seen below.

My collections are already connected with Name property added to both.

what am i missing?

Current voucher item > voucher category > name Contains
form input (drop down)

Thanks. I realized I couldn’t filter between to collections with a many to many relationship.
