YOAST plugin breaks store area of wp-admin

Hi,
Hope that you are doing well,
I am using the Clipper Themes from AppThemes *(my website: https://www.popularcodes.com). And my store area of wp-admin is broken when I using your plugin. It doubles the store description. I filled the description section but it seems that Yoast SEO could not read. Yoast SEO content analysis always reports that:
– Bad SEO score The text contains 1 word, this is far too low and should be increased.
– Bad SEO score The focus keyword doesn’t appear in the first paragraph of the copy. Make sure the topic is clear immediately.
– Bad SEO score The copy scores 0 in the Flesch Reading Ease test, which is considered very difficult to read. Try to make shorter sentences, using less difficult words to improve readability.

I tried to contact with Appthemes and they replied me that:
“From the first glance it’s related more to Yoast plugin more than to our theme. I just checked this plugin with clean 2016 theme and it has similar effect: When the plugin deactivated – plain text term description area, when the plugin activated – TinyMCE term desc area. It converts description editor to tinymce (even if it’s already converted by us), but we don’t ask for that, right? And i can’t find where i can switch it off.

Facts:
1. Our themes and Youst plugin both converts term description to tmce editor.
2. We use native function wp_editor() for that, we are in white.
3. Yoast uses javascript tricks…. dirty.
4. Yoast should ensure that his tricks are safe enough.

So, probably, would be correct ot ask Yoast plugin developers how to disallow convertation term description to tmce editor by his plugin.”

So, Could you help me to fix this issue.
NOTE: I am using the latest version of Yoast
Thank you very much!

Best Regards,
