Cant't edit/remove a (second) popup hidden from shop customize options.

[AIKLO]

1st

2nd (screenshot from english version, but also appears in spanish one)

  The 2 different popups:

-the 1st shows up as editable, from popup section. Can be disabled. Correct info written.

-the 2nd just shows up, but can't find it in any editable section. Cant be disabled. Don't know where it comes from, and it shows an old 15% offer that now should be 10%. Dont know if its somewhere in the code.
