[Résolu] Hebrew translation automatically overwriting english on random posts at random intervals

Background of the issue:
I am trying to debug posts' descriptions automatically changing. The issue can be seen on this page: lien caché

Symptoms:
Hebrew translation is automatically overwriting English on random posts at random intervals. For example, I input the English description manually, but it reverts to Hebrew the next day. This is happening across multiple post, regularly.

Questions:
Why is the Hebrew translation overwriting the English descriptions?
How can I prevent the descriptions from reverting to Hebrew?
