Issue expanding map to 4/4

I’m trying to create a north facing map from a point just past the central north point of a previous map I made. 3 out of 4 expansions work normally, but after expanding to the 4th stage the player location marker flips 180° Thus creating a copy of the previous map I made. I didn’t change position of where my avatar was facing while expanding the map.

 

(attached photo shows left hand previous map, right hand new map after sizing up.)
