Neoreader 2.0 / Firmware 1.9.0 : Navigation setting not stable



Context with a PDF after using the crop functions : ‘By Rect’, ‘Crop page’, ‘Crop Width’ or by Navigation -> More settings, etc. with a setting for ‘Navigation Mode’ done to ‘Crop = Auto, Column = 1(first choice), Direction = only linear’.
All options of The ‘Touch Binding Setting’ are set to turn the pages only.

Circumstance : frequently when a page is turned, the displayed page is moved without rescaling anything.

Problem : the setting for ‘Column = 1’ is lost and is set to ‘4 squares/4 parts’. After, it’s not possible to change the page, it’s necessary to go back in the setting for the crop functions.

Thanks in advance for your help.
