PowerQuery Parameter Multi-Select Reverts to Single-Select on Refresh bug

I have one sql table in direct query mode, and one Power Query Paramater of type Any. I can go into the Model and assign one of the columns to the Paramater and select "Multi-Select" and everything works. I can publish to the service and multiselect works, but if i click Refresh on the desktop the Multi-Select turns off and it goes to a single slection...Tried playing with the Visualization->Visual->Slicer settings->Selection->Single Select  but that does not work. Seems to be a bug...able to reproudce on new files easily. See below for screenshots of steps.

Hi @cgrundy ,

 

If your use cases require multi-selection (passing multi-values to a single parameter), you must toggle the switch to Yes and ensure that your M query is set up properly to accept multiple values in the M query. Here's an example for Parameter1, which allows for multiple values:

 

vkkfmsft_0-1652775386922.png

let
    SelectID = if Type.Is(Value.Type(Parameter1),List.Type) then Text.Combine({"'", Text.Combine(Parameter1,"','"),"'"}) else Text.Combine({"'", Parameter1, "'"}),
    Source = Sql.Database(".", "CaseTest", [Query="Select *#(lf)From Query1 where test in (" & SelectID & ")"])
in
    Source

If the problem is still not resolved, please provide detailed error information or the expected result you expect. Let me know immediately, looking forward to your reply.
