How do I fix effects saving issue

I'm using layout effects in my project. First, I used the "vignette" with start radius 0 and end radius 128. But I want to change it... and everytime that I put the end radius to 88 and save the project, this information isn't saved!

What can I do?

Use a global Variable to store the value and link the Vignette amount to the Variable?

I'm not trying to change it with events. I've just changed the values normally and saved the project... but this change isn't saved '-'

But now I think it's ok.. probably was a bug.

Thanks!

oh I misunderstood! That's weird! Glad it's ok now
