History Arrow not functioning properly?

Steve

Scenario: Reading Luther's Works Volume 44.  Have read through page 107.  Switch to NA 27 to look up Bible verse.  Look up Bible verse.  Use history arrow to return to Luther's Works Volume 44.

Problem: The history arrow does not always bring one back to the correct page of Luther's Works Volume 44. 

I'm not sure how the History Arrow functions, but it doesn't seem automatically to record the last place one was in a particular resource as the "list of book covers at the bottom of the screen" in the former version always did.

This also makes me wonder how the new version syncs with the desktop version as far as recording where one is in reading a particular document.  I haven't tested this to find out.
