Grid Livebinding glitch

I absolutely love the grid component. However i have this one annoying issue with it.
I use a lot of livebindings to make things easier.

The problem applies to TAdvStringGrid and TAdvColumnGrid for Delphi 10 Seattle.

1. Start a new project.
2. Drop a TAdvStringGrid
3. Use the LiveBindings-Designer
4. A Dropdown box will appear in the top left.

The box appears when clicking on the component in the livebindings designer.
I made a short video:

It doesn't matter if you link the livebinding to a dataset or just click it (like in the video). The combobox will appear.

You have to reopen the project (or restart Delphi) to make it disappear.

We have seen this issue. It's unclear what the livebindings designer is doing that causes this. We're investigating this.

I logged the window messages and noticed these get called when the dropdown appears:
