Cannot select the needed OData collection from drop down list in WebIDE

Hi experts,

When I try to create Fiori application via wizard in WebIDE, I could not select the OData collection I need from the drop down list.

I can ensure that the metadata for my OData service is returned successfully in Chrome network tab:

I have pasted the response of metadata request to a local file and opened it as below.

Let's say there are number of M OData collections visible in metadata response but I could only see N of them , N < M.

For example I could like to use the EntitySet "Opportunities" in my Fiori application, I can see it both in the metadata response and also in the model folder of my generated project:

However I could not find in in the OData collection drop down list during new application creation phase.

Perhaps the attributes such as "sap:addressable" does some trick?

So basic if I could debug the logic where and how the WebIDE framework parses the metadata response and render it as the drop down list, then I could find the reason. Unfortunately this seems impossible since I guess the parse is done in server side that I could not debug?

Any suggestion from your side is highly appreciated!
