Cache setting in advancedsettings.xml ignored



I’m trying to change my cache memory size, using this guide https://kodi.wiki/view/HOW-TO:Modify_the_video_cache
I’ve upped it to 1GB, but task manager still has Kodi using 100-150mb, and I can’t notice any changes in Kodi itself.

Suspiciously, the log file says:

log:
info <general>: New Cache GUI Settings (replacement of cache in advancedsettings.xml) are:
                                                     Buffer Mode: 4
                                                     Memory Size: 20 MB
                                                     Read Factor: 4.00 x
                                                     Chunk Size : 131072 bytes

Seems like the cache setting is getting ignored? How do I change the cache settings in Kodi 21.0.0?
