'wifi: ampdu: ignore deleting tx BA0' on IDF 4.0

[Mickael]

Hello,
I'm using IDF 4.0 and I got this error wifi: ampdu: ignore deleting tx BA0 when my colleague connected in Access Point on the esp32 from his PC. I looked in the forums but they say it's a problem already fixed in IDF version 3. I don't understand why it appears, can someone please help me.
I don't get this error when I connect from my PC or MAC, even on another colleague's PC there was no such error, so why only on my colleague's 1 PC ?
Thank you
