Two forms are created

The question form has two forms.

(Since I am Japanese-speaking, the site is also in Japanese. The title, category, text, and tags are displayed from the top. Two each are displayed.)

I wrote only one shortcode for [anspress].
There are no anspress or javascript errors.
It was working normally until the day before. I haven’t made any changes today.
I rewrote the shortcode again and saved it, deleted the cache, refreshed the page, etc., but it didn’t work.

Please let me know if there is a way to fix it.

thank you for reading. I’m sorry if the English is difficult to understand.
