Android player settings not always saved

If this is a known bug, please point me in the right direction.

Some of the player settings in Unity get lost when I build my project. For example, if I change the Bundle Version Code and then build, the version code will usually revert to it's old value.

Another setting I've had problems with with is the Splash Image (using pro). I can set a splash image, but it doesn't appear in build. After building there is no splash image set in Player Settings.

Any ideas what could cause this?

 

Typical, just after posting I found a solution! It seems the problem was caused by having multiple Inspector tabs open.
