Try resetting the Preferences to defaults.

I resetting the Preferences to defaults and try again,the problem stil there,am i miss somthing?

It works for me. If I type a text and then move to the left using left arrow key, text expander still works. Try to reset the Preferences. ex:i have ;fa string that will output as @ when i use this in the middle of text,it will not work https://gitee.com/lbgws2/myfile/raw/master/GIF%202022-2-18%201...

Maybe I'm not clear enough

I mean, when you use the arrow key move into the middle of the text, the text expansion fails, but you can use the mouse click into the middle of the text and then use the trigger word, which is available

text expander work well in the end of text
but when i move cursor in to text,it's not working
is a bug or need to setting?
