2Checkout Gateway not showing up in payment settings

Hello,

I’ve updated my old version of Jigoshop to 1.15.5 from 1.8.6 and seems that my Jigoshop 2Checkout Gateway (actually 1.2.2 version) does not work properly. It figure out as activated but got this warning on my wordpress dashboard:

Update Jigoshop to version 1.3+ to enable the 2Checkout gateway.

Jigoshop is already updated to 1.15.5 but 2Checkout Gateway not showing up in payment settings. Also I saw that the current version of 2Checkout Gateway is 2.0.2 but it’s not present the ‘new version’ alert into my dashboard.

Do you have any idea about it?
