There are 3 possible reasons why this is happening:
1. Filters: Maybe a new filter item was added to the app and to the modules but was not assigned to your account. As a result, you don't have all the necessary filters to be able to edit the content;
2. Rights: Your admin rights do not give you permission to edit the content;
3. Editable by others not checked: During the creation of a learning page, the person responsible for it is able to check or leave the editable by others field unchecked. If this field is unchecked, only the creator of the content is able to edit it. Check the article What does the "editable by others" checkbox do? to understand better this functionality.
In all three cases mentioned above, the best thing to do is to contact the main administrator of the app and ask her/him to check the 3 possibilities.
