In the calendar, I can’t change the priority for a process in which it is not possible to transfer to a stage

I went to the calendar https://baza.cn.ua/dashboard/?filtershowprocess=&filterdelivery=&filtercustomoplatacherez4=&filtercdatefrom=&filtercdateto=&filterdatetofrom=&filterdatetoto=&filterdeliverynote=&filternumber=&filtername=&filterproductid=&filterproductname=&filterclientid%5B%5D=&filterauthorid=&filtermanagerid= 91&filterdeletedid=&filternovaposhtastatus=&filtersumfrom=&filtersumto=&filtercode1c=&ok=1 Further along the process I want to change the priority Like this http://prntscr.com/ueiulq For processes that have the ability to transfer to some stage everything works, priorities are displayed But if I click on a process that does not have a stage for translation, that is, there are no stages for manual translation, then I see this picture http://prntscr.com/ueivtk, that is, emptiness Somehow it is very similar to a bug, since I need to change the priority, not the stage
