Model - Field properties not showing when added a Direct Query Table and saving the file/reopening

Yes, I think Redwoods pinpointed the issue and the temporary workaround. It seems the issue is caused by having a combination of parameters in the model where some are used in dynamic parameters and others are not used in dynamic parameters (and by the way, it's still occurring in the July 2022 version).

In my models I use standard parameters for the server and database name to allow for easy repointing from development to production. These are not used in the dynamic M queries. When I removed these parameters, hard coding the references into the queries - leaving only parameters that are used in dynamic M queries - the field properties are once again displaying. 

v-cazheng-msft - it should be pretty straightforward to replicate these conditions to confirm the problem. Although it's a relief to know there's a workaround, it's clearly not great to be forced to not use 'non-dynamic' parameters when making use of this feature.
