🐛 [BUG] - List Format Allows Multiple Buttons After Switching from Carousel

[Emnaghz]

Description

When displaying a List, only one button should be allowed in the List format. However, the following steps lead to an incorrect behavior:

• Switch the display format to Carousel.
• Add an additional button.
• Switch back to List format.
• Save the changes.

Observed Behavior: No errors are displayed, and the List format incorrectly allows multiple buttons to exist, violating the intended single-button restriction for List format.

Expected Behavior:

When switching back to List format, any additional buttons should be automatically removed, ensuring that only one button remains. The system should enforce the single-button limitation for List format, either by validation or by displaying an appropriate error message.
