Members are not being added to research list when adding a selection. After adding the selecting and saving the list, no members appear. However, if you add the member on a one off basis by clicking on the Add member button and saving, then the member appears in the list. This occurs when creating a new query or editing an existing.
Additionally, after adding the query and then saving the list you will sometimes see a notification on the top saying "Research list refresh is in progress", however it will never finish and add the members.
Download and install the latest patch which contains all fixes from previous patches. If you are running an older version, download and install the latest version and then the patch.
