I’d suspect the toner. I usually gold tone my Kallitypes and that toner definitely does not last.

But assuming it’s not the toner - has the pH of any of your solutions changed? IIRC density is affected by pH of the sensitizer pretty easily.

For the past couple of weeks I have been trying to make Kallitype prints but the DMax just is not there. It is hard for me to imagine that the platinum toner is going bad after less than a year but perhaps that might be the case?
