Thank you!
Actually, the "add" button was there, but it just added an item to a current kit.. I thought there is a different "add kits" button you are talking about... but your filter solution helped my issue, it was actually on.. on active fields only, so i did not see the GK away and third kits in the list, after i turned it off, there they were.. now i can use the "add" button properly..
Thank you! You have no idea how long i was trying to solve this thing!
Have a great weekend
