PC Hp1 Switches 500hz Monitoring To 1000hz Monitoring

The bug:
On a RE50 service from Dresden to Leipzig on DRA, after passing a Vr0 right before Coswig, I stopped at the platform there, right in front of the Hp0. At that moment, since I had passed a 500Hz magnet, the 500Hz light was still lit. After loading passengers, the Hp0 had become a Hp1, and I started driving. When passing the Hp1, the 500Hz light went out, but the 1000Hz light turned on instead. Because of this, I could not get out of restrictive mode, and I was required to drive below 45km/h. After the 1000Hz light finally went out, I tried PZB frei, but this did not remove the 45km/h restriction. This is clearly a major PZB bug that needs fixing.

How to recreate:
In the DRA journey mode, select the RE50 service from chapter 9. Turn on all safety systems, and keep to the timetable up to Coswig (where you stop in front of a Hp0). When the Hp0 turns into a Hp1, pass the signal.
