Comparators may misread a double chest after relogging

Idk why this happens but some times the redstone is not getting powered nor powering the repeater on signal strength 2 upon relog. U devs can see what I mean by watching the video in the attachment. Due to this bug my contraption won't work at all.

 

Steps to reproduce:

 

Fill a double chest with 3 unstackables and 51 stackables items, this should give a signal strength of 2. I will provide an image how to build exactly how I did in my testing world. Once built log out and log back in until this bug happens.

 

Expected results:

 

Upon relog the redstone dust MUST be powered thus powering the repeater.

 

Unexpected results:

 

It will give an output of ss1 instead of ss2 and won't power the repeater.
