meta box builder layout went wrong

Hi there,
We are now having some problems about the back-end of our woocomerce pages.
The settings of meta box should be collapsed by default, like accordions, and the options below should be showed only after clicked, but now the sub options of the service block settings are all expanding, and the page becomes very long, which is really weird.
More details please check the photos below.

Please help check.
