Problem with bullet point in TADVRichEditor

When i use BulletPoint in TAdvRichEditor, i've got this message (stack trace eureka log) :

Opération de pointeur incorrecte.

Delphi 12.3 - TAdvRichEditor v.1.8.10.2
Step to reproduce :

  1. Enter text on multiple lines
  2. Add bullet point by Toolbar on multiple lines
  3. Remove bullet point and continue typing
    Save and close form, i've got the message.
    It'is possible to reproduce with the project demo UDBAdvRichEditorDemo

Thanks

I tried a lot of times to reproduce this but could not get an error.
Can you perhaps record a video so I can see the exact steps?
