Trees suddenly stop moving,Trees made via terrain editor stop moving

Hello, I am currently facing a terrible problem with my level scene. The first time I opened unity and started working on this scene, I placed trees which were moving without inserting any wind zone. Then I saved my project, closed it and reopened it in few hours. When I opened it though, my trees now stopped moving. However my grass is still moving. I added a wind zone but it didn't help. I've placed all of the trees via the terrain editor. I am uploading some pictures of terrain's settings. Currently I do not have a screen recorder, but I will upload a video if neccessary. Any help would be appreciated.
