Good morning, I'm using Umbraco version 12.1.2. I have a problem displaying the toolbar (Richtext editor) in the "Row configurations". In the data type "Content Base - Content - Grid layout", I added a row configurations called Double (made up of 2 cells of 6).

Once recalled in my content, if I insert 4 Richtext editor type contents in the first row and then do the same in the second row, the toolbars of the second row disappear when saved. In the image, I have highlighted the missing toolbars with yellow.

I can't understand why. Can someone help me? Thank you
