I can't help you because your VI is in LV 2016 which I don't have installed. If you saved it back using Save for Previous Version by a version or two, then I could look at it.
I don't know what you mean by "only until 1 execution". If you want something to appear into a string indicator, let's say during 1 iteration of a loop, then not be there during the next iteration, then you need to write an empty string to that string indicator on the following iteration.
