To add: You very likely have *mistakes* in your script that make you *think* a certain block is repeated.
What could those mistakes be?
#1: You have <block>s that run the wrong <likert>, i.e. something like
/ trials = [1=person_3]
#2: You have <likert>s that display the wrong <picture>, i.e., something like
/ stimulusframes = [1= pic_3, cue1]
#3: You have <picture>s that display the wrong item
/ items = ("3.jpg")
