Bug in all_before_repeat?

Hello everyone,

I am creating an experiment right now using a table for each task of the experiment. The tables contain all trials needed for this experiment and I do not want any of them to be repeated.

Every block has the "add on" all_before_repeat behind the number of trials. I have run the experiment at its current stage several times with either the maximum number of trials (length of each table) or less trials and sometimes it appears to work for some tasks as the data at the end does not contain repeated trials but then other tasks have repeated trials.

For example, in the following task each row should only be called upon once and in order to check for this I save "TABLEROW". Now see this:

Sorry for the small image. As you can see in the last column - rows are repeated. This should not be the case as my code for this block is as follows:

block VS
tasklist
search1 10 all_before_repeat
end

Has anyone else the same problem at the moment and found a solution? Thank you.
