Unexpected behavior of For loop - bug?

[omas]

Every time i run the code, data from for loop index tunnel adds new data to the previous run, but only in one of the two for loops.

Is there anything I'm overlooking??

I am running Labview Community Edition 2023 Q3 32bit 23.3f0

I have attach a vi saved in 23Q3 and one saved for labview 19.

Not a bug. It is the uninitialized shift register of the middle for loop. It keeps the values of the last run, letting the string array grow.

Initialize the shift register with an empty array.

Nice catch! I had completely overlooked that 🙈

Thank you

Best regards
