You've likely entered the 2nd chord for each bar in the 2nd half of the cell.

That second half is reserved for the 3 and 4 beats of a 4/4 bar.

2/4 is accomplished by entering both chords in the first cell of each space only.

Separate the chords with a comma when typing:

ex: |C7,F //|

and leave the second cell empty.
