Fixed the shotcode in the B2BKing wordpress plugin, so that multiple shortcodes can be installed on one page

WordPress, with Flatsome Theme
the plugin used is B2BKing

The problem is the B2BKing shortcode for registration.
https://woocommerce-b2b-plugin.com/docs/b2bking-shortcodes/

We'd like to have more than one shortcodes on one page
For example, I created two shortcodes in one page, namely:
[b2bking_b2b_registration_only registration_role_id=699]
and
[b2bking_b2b_registration_only registration_role_id=696]

and I put it on this page:
https://exportindonesia.id/test/

What should/expect is:
shortcode with id=699 will display txt field "699" and
shortcode with id=696 will display txt field "696"

But what happens now is that the shortcode that is installed above will affect the shortcode that is below it.

So if the shortcode with id=699 is installed it will display the txt "699",
but the shortcode at id=696 installed below it no longer shows txt "696" but displays txt "699"

On the other hand, if a shortcode with id=696 is installed above, then other than that what appears is txt "696,
shortcode with id=699 will also output txt "696"

Later this shortcode will be installed in the acordian function on flatsome.

After completing this problem, Freelancers need to show the css or code that was changed or added
