There are so many things going on the IADP backend with submissions and validations and at this moment I can't state specifically how long it might take for such kind of changes. Sometimes it appears the next day, sometimes after several days. I cannot confirm this now.
I would suggest you keep tuned up and watch for it. Also since the whole program is Beta, there may not be a definite answer to your query yet.

Perfectly acceptable answer considering the Beta aspect. Thank you Rooven.
Just a quick update. Meta edit changes seem to be propogatong in 1-3 days. That is not bad considering the load the testers are under. Thanks everyone.
