Flashback X4 mono out

Flashback X4 mono out

Hi there!

I bought a flashback x4 in second hand. It is importante to say that the pedal is in mint condition, as new.

Although, I have an issue…

I use only the mono input, so, by logic, I have to use the mono-out (’cause I don´t use pedals in stereo mode).

But, the mono-out only plays the dry signal without any delay.

I’ve tryed connect to the stereo-out, and it plays the delays.

Is this a firmware problem?
Is this hardware problem?
Is this any configuration that the previous owner could done?

Thank you for your time and your help.
(sorry my english)

Hugs
