Hello, Zeal Evince,
Thank you for the response.
We recommend that you navigate to XStore > Theme Options > Speed Optimization > Menu Cache, Static Blocks Cache, Remove Query Strings From Theme Static Resources, and set them to Off.
Clear the cache and check if your changes can be visible after that.
If the problem persists, please record a video for us.
Thank you for your cooperation and we look forward to hearing from you soon.
Kind Regards,
8theme team
