Problem:
There were following 2 issues:
A) "Clear language information and repopulate languages" message.
B) "WPML didn't manage to translate this page" message.

Solution:
A) About "Clear language information and repopulate languages" message, it was a false positive, so I removed it from database. I used a 3rd party plugin (WP PHPMyAdmin) and followed the steps mentioned here https://wpml.org/forums/topic/cant-clear-language-information/#post-11052203.

B) About "WPML didn't manage to translate this page" message. In fact, I got "WPML tried three times to translate this page and failed" message when I tried to translate a page. So I followed the steps mentioned below:

0) I added myself as a translator in WPML -> Translation Management -> Translators.
1) Visited WPML -> Translation Management Dashboard.
2) Chose the Page to update the translation.
3) Sent it to Translation Basket.
4) Visited WPML -> Translation Management -> Translation Basket.
5) Sent it for translation, by choosing myself as a translator.
6) Visited WPML -> Translations and translated the page by clicking the “Translate” button.
7) It took me to the ATE (Advanced Translation Editor), where I found that French side was empty. So I tried my best to fill in the French translation as better as I could.
8) Completed and saved the translation and now page status shows pencil icon instead of gears or in progress status.
