After applying prefab change. All GUI elements centre themselves inside panel 4.6 Beta v 20

Just wondering if anyone else has been experiencing this problem.

I have been working with the new 4.6 GUI for about a month, so when version 20 came out I upgraded that day.

Ever since then, whenever applying changes to my main canvas prefab, all element (text, buttons ect) inside each panel reset to a central position inside the panel.

I have already submitted the bug report, but was wondering if anyone else has experienced this problem and has found a solution.

All anchors have been set manually, and this problem wasn't happening in any previous version.

here are some example screens...

So once I apply prefab changes my lovely panel on the left is converted to the panel on the right.

Only way to fix is if I quit unity & chose 'not' to save changes, then luckily it is reset back to normal (otherwise I would have to build it from scratch).
This happens to every single panel inside the canvas.

Just wondering if anyone else has encountered this issue and could suggest a solution.
Cheers
