I recorded multiple tracks in audacity but when I export it all of my reverb effects get a whole lot more echoey. When listening in audacity it sounds perfect. After the export there is way too much echo. I have tried exporting in WAV and MP3 and listened to it on my computer and also tried sending it to my phone too. Please help!
In Audacity some VST3 plugins revert to their default setting when they are applied* 
A possible workaround is to save your settings as a preset in the plugin, so it remembers them.
[ * export or mix-down applies the plugin effect ]
