Weird behaviour when adding a new listing

‘Hi,
in MJ theme when I try to add a new listing, I’m shown a modify/edit screen for my last inserted listing.

I noticed that if in pages->add listig -> edit I change the layout to [ADD LISTING (old version)] it works ok and I’m able to add a new listing, but when I revert back to the default [ADD LISTING] I’m still shown the list editing page.

Does it ever happened before? Is there any mistake from my side?

Thanks
