Legends when using parameters not sorting

Hi everyone, 

I configured this portion to interact with the parameters from its top 

here are my parameters 

and both of these I'm grabbing from tables where the sort orders were already defined

but when switching to parameters, the legend order resets itself alphabetically 

this does not follow the sort order I've indicated from above. Anyone here who knows what to do to have my legends ordered as indicated? Thanks in advance!
