More Qs:

There is something asymmetrical about the sides of the cabinet at the bottom.
The photos of the bottom are taken with the very bottom sheet taken off after I removed the tacks - there was no glue.


Notice the inner side lining sheet well-aligned on this side of the cabinet.
   
Not so aligned here - goes in between the outer siding and the base.
So it gets closer to the bottom.
   
As the result the bottom is inclined on this side.
   
Whereas on the other it is leveled.
   

So before I glue anything I'd like to understand how to even it out.
I tried to apply an effort to pull the bottom down and to release that inner side sheet - no, it wouldn't move, Any stronger effort I felt would just rip the bottom out. Could it be someone tended to the cabinet and glued and tacked everything this way?

Also the bottom sheets you see on the last two photos, they do not have any glue holding them in between them and the base either. However at the edges something holds these two sheets (the bottom sheet left now is two pieces, you could kinda see a part of the gap between them on the last photo at the right bottom corner) and does not let them just come off and reveal the base.
