We reproduced the issue locally.
No issues with the chart itself. When a category menu is initialized for a description string, it's not being updated either when removing or inserting a card. To work around this, until it's resolved through a software update, you would need to reset the "Local Settings" for the chart plotter to reinitialize the category settings for that description string. For a null description string, since those charts are typically embedded, this would require you to have the card inserted when resetting those settings.
