Rapid stamina drain in recent event players

For the past few weeks, I have been noticing rapid stamina drains in players from ballond'or and other recent player items. Bellingham with 5 star stamina would run out of gas even by half time. r9, ronaldino and other ballondor event players would be red by 60-70 mins. Anniversary, trick or treat etc event players would be going good till the game ends. It might be a glitch that needs attention.
