Quality Size Limit not saving

After changing the quality size limit and clicking save. the pop-up confirmation are displayed, however after refreshing the page the values are back to the pre saved values. Any thoughts?

Working fine for me on the latest develop/master release (1065/1066). Looks like the values change a when the server calculates them, but its within a few megabytes only.

As an example i will set SDTV to 188.74 and 377.49 and click save. After refreshing it says 220.20 and 440.40. Not exactly sure, but this seems like unexpected behavior.
