Api Stats response with only one display information

Hello:

I have connected some displays with xibo-cms.

When I want to make a query about the statistics of the screens, just answer with the statistics of a display.

the previous picture represents the configuration variable.

The displayId variable is 23 but Xibo-cms response me with id 15.

Thanks in advance.
Best regard.

Would you mind showing the full request and response so we might understand whats happening? Also what is your CMS version please?
