TotalFinder Columns shifting every folder selection (video linked)

Bug:
In Column view, when viewing nested folders with columns that extend beyond width of full window, TotalFinder keeps shifting it’s content to the right every time a selection is made via both keyboard arrow navigation and clicks.

Linked is a screencapture video demonstrating the glitch via nested dummy folders:

TotalFinder config used in demo below: window in visor mode, pinned, with automatic column widths active, and folders on top - in case any of this is contributing to the glitch or helps narrow down the cause.
