Image-Filter does not keep band unit

Version 9.0.6, all latest updates. (9.0.4 - same behavior)
Tried to run old xml graph (Image-Filter – GoldsteinPhaseFiltering) and got error “GoldsteinPhaseFiltering band requires a unit”
Not sure when it worked last time, but it worked.
Now band unit after Image-Filter OP is empty. There are some changes in createFilterBand() but it looks correct
Any thoughts?

Hello @traktor,

Can you attach the graph you are trying to run ?

newgraph_onlyfilter_gld.xml (2.6 KB)
