Can't use ADSOs in composite provider

Hi all,

After auto upgrade of HANA STUDIO components i can't use ADSOs in comp.providers any more. "Add provider" button returns no ADSOs at all (despite the are some in EDW). Simple drag-and-drop of specific ADSO to comp.provider returns the error:

The strange thing: it's not a problem to add any of standard DSOs to com.prov. either via search or via drag-and-drop.

The version of HANA STUDIO env.

Can anyone help with solving that?

Thanks.
