Can't create an app based on BW Odata service

Dear support,

We've tried to create OData service based on BW Query in Eclipse.

It worked well on the ABAP side. Generated OData service ZTEST_DEMO_QUERY_SRV returned all the data in the test mode:

Now we want to create a simple SAPUI5 app in Web IDE based on this template:

We see this new service in the list of available services:

Besides we have pretty strange properties names I would go further just to see values. But we can't do this because of empty list of empty  field OData Collection. It's not possible to choose anything there.

This template works well with all other OData services but not with generated from BW. To be honest I do not know where should I write about this problem, to BW support team, or to Web IDE support team.

I assume as OData service is working and it even provides correct column names in metadata file I guess the problem is in Web IDE.

Could you please check that? See metadata file in the attachements.

Thanks!
