Some repositories are missing from the tree view

When sorting by repo type (this is the default sorting) some virtual repositories may be missing from the tree view.

When sorting by repo key, those repositories returned (in the ui rest) with the value of "repoType=Virtual", while others, the ones that are visible in the tree returned with "repoType=virtual" (mind the lower case).

I could be related to "continueState" value, although I got 500 results in the response, The continueState value was 1382 (I didn't use any filtering).
