Actually answering this for anyone who also got curious and found this thread.
You need to select the EQ preset (for the specific track you want to be EQ'd automatically) and enable the equalizer first, before playing the track. If the equalizer isn't enabled, the preset won't work.
So if you use EQ presets in specific tracks, you should keep the EQ enabled at all times, even if most of your tracks don't use it.
One last thing, if you're playing an EQ'd track and open the EQ settings, you won't see the preset it's actually using, but rather the default one.
