Why does this sink?

I have tried innumerate ways to just get a solid body to float and the only way I found was to manipulate the value of gravity within the free surface setup.  With all the values set reasonably, and using materials that are significantly less dense than water, I keep getting a sinking behavior for the objects. 

Any ideas?  I've attached video, pic, and archive of the setup. 

Please and thank you.

@tymoteusz_lasko  Could this be another bug in the code?  In the free surface dialog if I change the value of gravity to 9.81 (even though the units listed are cm/s/s) then a float simulation performs as expected (this is a ball of soft wood in water):

This is a bug in the software (just in the user interface).  When performing a free surface analysis CFD labels the units of gravity as cm/s2 when in reality it's in m/s2.

TLDR:  Use 9.81 as the gravity magnitude even though the free surface dialog box says cm/s/s
