Completing a sprint results in completion of a sprint of that project and another project

Question

I have two projects with me. 
A project called as CRM and another called as a portal. Both these projects run independently and there aren't really any dependencies between them.

There are 3 open issues in The portal sprint. And there are 33 open issues in the CRM sprint.

Ideally when I complete the sprint on any of these boards it must show data of that board.
But when I complete the sprint of Portal, I see data of CRM on it. Image displayed below.

The 33 issues are of another project (CRM). 
I have only 3 open in portal.

If I click on "Complete sprint", it completes the sprint of this board (portal) as well as that of CRM.

Not sure if this is a bug or if there is a setting I am not aware of.

Yes it's a company managed project.

There is nothing filtered here except for the project.

@Geo Mukkath , I was referring to the board's filter. Is this a Company managed project (look in lower left corner of screen). If so please click on the ellipses in upper right corner of the board and select board settings. Once in the board settings, select the general tab and look at the filter query for your board. Please share that filter here.

Hi @Jack Brickey ,
Thank-you for replying but I don't see anything being filtered in any of those boards.
