Hello there
I am facing a problem while designing.
When using Flexbox, I drag and drop directly without clicking the add (+) button.
After making the necessary adjustments to the main section, when I try to save, the changes are not saved and the message shown in the attachment appears.
Please check the attached images; you will find everything explained there.
Finally, thank you very much.
We await your solution to the problem, and as always, you are outstanding.
