Text assigned to a string variable doesn't update when that variable changes.

I use variables for a multilingual project. 

I’m using a file as library to manage string variables. I tried updating some strings in the library file but they didn't carry over to the local usage file which already updated the latest library. The text there is still showing the old version instead of syncing.

I need to re-assign the same variable to the text so that it can show the latest version. It is very annoying.
