Translated website showing default language’s description while sharing

My default language is English and translated one is Nepali. And I am using Rank Math SEO as SEO plugin. When I edit Title and description of any posts in default language (in SEO plugin area) to alter how it appear in search result I am having issue with translated language. Those alterations are appearing in translated language too.

When I share translated posts in social media below post title description appears in English language instead of Nepali language. If I it appears like that most of the readers wont click on the link to read because they think the whole content is in other language and I had change just post title to Nepali language to get them click on it by fooling them. Many are doing this kind of misleading stuffs.

Those alteration should appear in only original language. And I cant figure out how to change it for default language too. As I have to make the post title and description different from post topic in search results or while sharing in social sites.

Is there any way I can choose to change these areas in translated languages as well?

Here is the screenshot of this issue. I had attached 3 pictures in this screenshot.
1) what I have written in posts (default and translated one)
2) changes I did for SEO in default language
3) How it (translated post) appear while sharing/search result.

I am just afraid, can we use SEO plugin for default language or not? I did not find it any where. If yes I can change those words or sentences from there in each posts.

Thank you
