Most likely you have used different EU LOGIN accounts for your applications. This is the reason why not all of them are visible if you log into one of those accounts. This is not a problem, but please be aware that if you have a temporary contract with an EU institution that uses SYSPER and if your contract ends before the conclusion of the competition, you must activate the ‘EU LOGIN for life (EUL4L)’ via SYSPER to keep the access to your internal account.
