Issues with supply cut and opensea

hi guys, i recently published an open edition. i need help if possible.

1.) i initially did 999 supply buy would like to cut to 69 supply. i did everything in the token settings but in manifold claim page it still shows 999 claim.

2.) in the opensea collection its showing 2. i might’ve messed up. i think its because i did the claim page as well as mint on mainnet. how do i get rid of it?

here’s the link i want gone in my collection:
