Viewer Zoom-In at Toolbar not working correctly

Hello,

In our .Net project with Groupdocs Viewer when customer view some file png or pdf they use Zoom in toolbar but its not working correctly.

For Example: Png photo file is displayed and I press Zoom-In + button and at some percentages it makes the photo blue color filter like some kind of link. It does this %120 or %180 or %200 just random percentages I guess depend on photo resolution or size.
And Another wrong behavior is at some level it reverse the Zoom-In. So it makes the photo more smaller when I press the Zoom-In + button.

I share the detailed screenshots and project and OriginalPhoto that I tried.

Thank you
