Its not a bug.. Its caused by User Error and/or how you are using LPX... and not having read the User Guide 🙂
You are likely running LPX in 'Garageband Pro' Mode.... and you are clicking on items in the library.. or using the automatic open Lib option... which are presets not instruments... Presets being a combination of, for example... an instrument plugin and certain FX plugins plus in some cases Auxes...
Time to read the User Guide.. (Hint Hint!)
But in the meantime... go to Logic's preferences /advanced tools and turn on all Advanced options.. Now Logic will run in the full LPX mode...
Now when creating a new track, uncheck the Open Library option... If you dont see that option click on the Details button in the new track dialog box...
Now a new blank track will be created...............
From the User Guide.... after searching for 'New Track'
