teststand 2012 preserves variable value

[ww12345]

I have a problem with TestStand 2012 which preserves variable value. I have a step and its settings in string variable. I use pre-expression at step like Step.Settings += "00". I run the sequence under sequential model and the problem is that Step.Settings is equal to "00" on first run, "0000" on second run, "000000" on third run and so on but it should remains "00" on each run. I cannot find the root cause. Did anyone has the same problem and can advice how to solve it?

Try unchecking the Sequence Properties>>Optimize Reentrant Calls to this Sequence for the sequence that contains the step.

It works good, thank you. I don't know why this setting is enabled as default seeing that it makes such problems.
