I didn’t uninstall or reinstall
I have the latest verson 5.8.8
I didn’t use it for a few days then when I wanted to run the macro, it’s all gone 
This plugin is like a student project, so buggy and release seems like QA is not done properly, a year back I had the problem where the macro get deleted when trying to save also and it’s so difficult to save, now this is fixed.
Here is another person have the same problem previously Lost macros after update
Super annoying.
