Role permission manager not working

Hello everyone,
I have multiple user with different roles, and i assigned them different projects via user permissions.
everything was working fine but since last few days, every user with is able to see all PURCHASE INVOICES, even though they can’t open it but it’s still visible, also they are able to see all the projects but they can’t open it.
Please help.

Note- i tried same settings in different erp and their it was working fine, maybe something is wrong with the module or role permission manager.
please share your suggestions.

Thank You

Please check the Roles and their permissions. Try to check role permission differences.

what is role permission differences, and i did check the role permission manager and everything is good, i even tried same settings on different erp next server and it’s working fine there.
