It seems that you (or somebody else) has changed the time period setting specifically for those resources. If you use "Edit" button on given resource and then change the time period settings from "Use time period from current view" to something else, the resource always will display only this time period.
So if you want to be able to change the time period setting from view, the resource must have this settings always on "Use time period from current view".
Thank you, jcermak! That was it!
So simple, I should have thought of it myself
