Number superposition

[l'andorrà]

I'm trying buttons and other object onchart for the first time and I found an unexpected issue. This is my current short project:

Everything works fine except for the dynamic value of the only variable I'm using. When I drag the EA on the chart everything works fine:

But just a few minutes laters a lot of numbers are superposed ia way that they can't be read!:

Could someone please tell me what's the problem?

@l-andorrà Any suggestion?

@l-andorrà to me it looks like the EA doesnt clear the value before putting new one on it. Don't know how to fix it, though

@roar This is what I thought initially and this is why I included a 'delete text' block. I will contact the admin to let him know. Thank you.
