ACF Plugin within Avada, Date Picker Error

Hello, I’m a beginner in WordPress. I’m using the Avada template, and in the process of adding fields to the Post using the ACF plug-in, other string fields are reflected without any problems, but only in the part where the value is received by Date Picker, Format (e.g., Y/m/d) is ignored and displayed like <p>20250420</p>. When writing on the Administrator page, the Display Format works well, but only Return Format is ignored no matter what format I change. I can’t see if ACF Filter doesn’t work, I can’t find the .php file one by one, and please help the WordPress masters to figure out what to do. Thank you for cooperation.
