Help button issue with 5* and 6*champs

Lately when I finish an arena round, the 5* and 6* champs I just used don't pop up with the help button on them it seems like they automatically get help asked for them, but when I log back in 10 mins later they pop up to the top of the list with the help button finally activated. Then I've got to take a few mins to go one by one and hit the help button on each champ, which as we all know takes forever lately. This doesn't happen with the 4* champs.
