Passive loss carryover (Box 2 income ONLY) from prior years split between Box 1 and Box 2a automatically, why?

I have passive loss carryover from the past 3 consecutive years (19,20,21) from SAME entity K-1 reported on Box 2 Only.  I've noticed that Turbo tax has split this amount between Box 1 and Box 2a each year (seemingly arbitrarily) and again in 2022 return when partnership was dissolved with GAIN large enough to offset all accumulated losses.  Without EVER having any Box 1 income reported from this partnership, why does turbo tax split the amounts btwn box 1 and 2?

 

I have several other non-PTP real estate rental K-1's with losses and it also splints passive loss carryovers in the same manner....as they roll from year to year.
