Cart Ajax – select type of shipping

I have a min cart total set with the limitation of working on “local pickup”. In my shipping zone I have two types of shipping: flat rate and local pickup.
The problem appears when I have to choose the shipping option in the cart, if I select one option and then change to other, it does it by ajax but the limitation is still there. I think there’s an issue between the condition that i’ve set in the plugin and the ajax reload of the shipping option.
Do you know if I can fix this issue with this plugin? Thank you so much.
