I am testing Xibo and have few issues with it while testing

Is that the longest duration on your layout? If so then that would make sense.

So player connects to the CMS each collection interval (setting in display profile), then download updated content/schedule. If you do make changes to the layout that’s currently being displayed on your screen, then after collection interval+layout duration it should show the updated layout.

mmm could you please check if you have fully qualified path to your CMS library in your CMS settings?

Other than that what’s the durations on your layout?
