Unable to save tier to pages after update

So i just updated my patreon plugin today and i could no longer keep tier saved on my old pages. It’s always showing 0 and refuses to change regardless of what number I put in. I’ve done nothing to the settings so far

Im not able to reproduce this with a new install or by upgrading from 1.4.0.

Precisely where does it happen? In a post page which the post was locked before for a certain amount? Or a post page which was not locked before? Or in a page?
