Doubling component on "Standard" palette page

Recently I've installed the new Embarcadero Delphi 10.3 Rio, and noticed that some components on the Standard toolbar page are being doubled. Particularly, the doubled components are TMainMenu, TActionList and others. These components live in Embarcadero's Standard package.

I've looked through the list of installed packages and found some Embarcadero FMX packages with these components. Unchecking those packages (need to uncheck two FMX packages) didn't give a result.

Any idea how to fix this?

If I let the mouse hover over the 2 MainMenus. I see "Name: TMainMenu unit: "Vcl.Menus" and "Name: TMainMenu unit: FMX.Menus" – MartynA
On my install copy, I see unit Vcl.Menus and the same package on both TMainMenu component icons. – Spectorsky

This is an IDE bug that affects only components in Standard VCL or FMX package.

Standard VCL controls are displayed twice on the Component toolbar https://quality.embarcadero.com/browse/RSP-19518

It is harmless, so you don't have to do anything about it.

Which standard package controls will be duplicated (or not at all) depends on the context.

If you don't have any application or package open, you will see both VCL and FMX controls on the toolbar (no duplicates). When you hover with the mouse over the component icon hint will tell you to which package control belongs.

If you have VCL based application or package open, you will have duplicate VCL standard controls. On the other hand if you have FMX based application or package open you will see duplicates from FMX standard controls package.

However, above behavior is not carved in stone. It is just what you can observe most of the time. Component toolbar behavior can be rather unpredictable at times.
