@kingsize thank you.
I think you're a pro and I'm just a newbie, I'm here trying to learn and I think I'm in the wrong place.
Is there anyone who can direct me to tutorials or forums where I can find my answer.
@marlo If you check append, previous file result won't be replaced, you probably have action, which doesn't have append checked. If you are 100% sure, that append is checked everywhere upload your project.
