adding grains in ounces

I am having an issue with adding grains in ounces on the New BeerSmith 2.3 trial version. I wanted to try it out first to see how different it was from the 2.1 version that I currently run.

When I tried to enter 15.1 ounces of 60L the new system auto corrected it to 1lb. In my current 2.1 it allows me to enter amounts very close to 1lb give or take a 10th of an ounce.
How can I correct this or prevent 2.3 from bumping up my increments ?

You can go to 'options' > 'Units'  and you can set the units to any unit you want (pretty much) and the accuracy you want displayed which will keep the software from rounding for any unit to that precision.
