F1 2021 Why the ERS was do that?

[Jediauf]

Hello, today i go to my career in f1 2021, and go into practice and started a ERS program, i do a lap without using ERS and on the last two corners the ERS are going down for not reason, it's bug or a feature that i didn't know about the ERS ?

how to fix that?

Its normal, ERS is always on, i mean, when you dont use it, its like on normal mode, so the battery still in use but on a lap, he will gain on energy. but when you put it on, its like attack mode

You have worn ERS parts and/or Energy Store. I can see in your vid you have orange and red icons for the powertrain in the MFD. I couldn't figure this out at first in F12020, replace the worn parts and it will work as normal.
