OG membership types page initially empty, does not show default

[izmeez]

When the OG module version 2.10.1 is enabled and you first visit admin/config/group/group-membership page it is empty and does not show the Default og membership type.

Only after adding a new og membership type do you see both the previous invisible Default (og_membership_type_default) and newly created type.

When first visiting admin/config/group/group-membership page it does not list any og membership type, not even Default. If user leaves fields empty and clicks on save and error occurs stating that the field is required. However, if the page is refreshed it now list Default as an existing og membership type.

While I have experienced this issue on a test site running php 7.4.33 it does not appear to be reproducible on a backdrop demo site that is running php 8.1.31
