Alpes de Zwift bug

Hi, firstly apologies if there is already a thread about my questions.

I have completed Alpes de Zwift already four times without any issues, though today, for the fifth time, as I started to descend, my speed could not get above 24 km/h. As it would reached 24 km/h, it always started counting again from 20 km/h.

Is it a bug, or am I doing something wrong?

Thank you!

Closing this one.

Ride On!
