Executing two times when using file change trigger activity

hello everyone

I’m trying to make Monitor Events using ‘File Change Trigger’ like this

It’s simple and no error.
But when i try to execute this one, ‘Message Box’ activity executes two times…

What is the problem???

My ‘UiPath.System.Activities’ package version is 19.8.0

Welcome back to the uipath community.

May I know how many text files are there in that folder ?

hi !

There’s 10 .txt files in that folder…
And…the real problem is that…
if i change ‘ChangeType’ property to ‘Created’, then ‘Message Box’ activity executes two times.
but changing property to ‘Changed’, ‘Message Box’ activity executes only once…
