Can't schedule post to business profiles that are linked to the account

I have a bunch of content in my shared projects calendar that I want to schedule for my business social media accounts.

These accounts have been connected by another team member and I can see them when looking at the 'manage connections' on the main calendar. When editing the post, the 'select channels' profile has them under 'personal calendar', and they are technically visible... but when I select the profile and hit save, nothing happens and nothing get's saved.

If I make any edits, they won't save if a profile is selected. Provided I don't try to select a profile, I can edit and save freely without issue.

I have looked at adding these profiles myself as I have full admin rights for these pages. However, when looking at LinkedIn specifically, when I connect Adobe Express, I can see profiles from previous employemnts that I have not managed for over 8 years, yet I can't see the current and ONLY profiles I am managing... anyone else experienced and found a solution to this?
