Tab filter function does not work properly on one page of Happy clone.

I give you the video.  I will be very grateful to you if you look at the contents in the video and give me a quick answer.

I don't think the video is attached, so I'm giving it to you through Google Drive.

I think it's because you saw the EN page. 
The tab filter is not working on the KO page. 
I hope this will be reflected on KO page normally.

Can you solve the problem on this page of my WordPress?
If possible, I will share the access account.
I will be happy if the tab is reflected normally.

I don't know how to watch debugs either. 

Is there anyone in your company who can provide technical help? 
I don't understand why this function doesn't work on the copied page, and I'm just angry what uses the service. 

Please connect me to the developer.
