What do you have you global beats set to under the gear on the upper right?
Here I have it set for 4 beats so that means with 1 repeat that is 1 measure of 4/4 time.
I my example here The first chord plays one measure, the 2nd plays 2 measures, next 1 measure and next 2 measures. If you have global set to 1 beat (just a guess based on your timings) that means your 5th chord is playing 3/4 X 2 or 6 beats. Is that what you want?
