HDR>SDR problem with Avisynth (PotPlayer)

Hello. I've been using svp4 pro for a long time. I have a problem with HDR videos on SDR monitor or when HDR is disabled in Windows on a HDR monitor.  (I don't use HDR because the HDR function of my monitor is not good enough, SDR looks much better.)

When the "remote control" option for avisynth filter is enabled, some of the HDR videos colors look like washed out. Not all videos. Some of them. I don't know what is the difference is. There is no problem at all when playing SDR videos.

When I turn off the remote control for avisynth or disable avisynth completely the colors look like the way they should but when I do that SVP4 does not working.

I tried to enable SMPTE ST 2084/2086 HDR Correction in PotPlayer, but those options don't do anything when avisynth and madvr are working. Those options only change things when PotPlayer settings are in default mode.

I've tried KMplayer. KMP with avisynth works fine with remote control enabled. Colors are just fine.

Could you please help me with this?
