Getting error while creating template

can anyone help me with this error while creating a template

Do you have any extra buttons in CTA? Sometimes we get this issue if there is an extra button in either of the section.

i have added two buttons as you can see in screenshot@Dimple_Mehta

Seems that there is an issue here. The mandatory fields of CTA are not getting populated and the button cannot be deleted hence causing the issue. Suggest raising a ticket.
