Bind to parameter is missing in modelling advanced properties for parameter

I had the same issue.

My requirement was to provide a list to the user where he selects a value which is the parameter to load a certain file depending on the filename.

I had only import queries. So in data modelling the bind parameter wasnt showing.

I just added one completely useless DQ query. The "bind parameter" showed up. I could take my parameter from the drop down. But it didnt worked. I went back to the data modelling and even though my table has a parametrized icon the parameter wasnt any longer in the drop down.

I went back to power query editor and changed the name of the parameter. Then it showed up again but still no functionaltiy.

I started a completely new report with the same logic but with DQ to a SQL Server and added the Parameter in the where clause. Everything works as expected. I can choose the value from a list which has the parameter binded and the report updates filtered by this selection.

So obviously there are data connection / data source restrictions but in my first scenario this "bind paramter" showup was very strange and somehow buggy.
