Contradiction with Exodus 12:37
This verse states the number of people who left Egypt, which may contrast with logistical feasibility involving camp movements at Tahath and Tarah.
Exodus 12:37: And the children of Israel journeyed from Rameses to Succoth, about six hundred thousand on foot [that were] men, beside children.
Contradiction with Numbers 33:28
If interpreted differently, it may suggest an immediate consecutive movement, which might seem logistically inconsistent with time elapsed in certain interpretations.
Numbers 33:28: And they removed from Tarah, and pitched in Mithcah.
Contradiction with Deuteronomy 1:2

Deuteronomy 1:2: ([There are] eleven days' [journey] from Horeb by the way of mount Seir unto Kadeshbarnea.)
