What does this mean and how can I fix it?

When I try to download my ex4 from the editor I get these errors:

I know it's something to do with the attached indicator, but I can't figure out which parameters...0_1588459786101_Baluda.SuperSlope.v.2.2.mq4

[SpecialFX]

@specialfx OK I get that it relates to the "string rede" parameter, but still no idea why this is a problem as it displays fine in the terminal...

This is a question for roar or miro, I'm afraid.
