Compost is slightly moldy

Mold is normal, and is an indicator that the natural compost processes are happening. Most gardens are full of mold just below the soil surface. It is generally non-toxic, but please be sure to wash your hands just as you would after handling regular soil.

In some cases, increasing the "brown" content will balance out the chemistry of the compost and dry it out slightly, which will gradually reduce the amount and wetness of mold. Try adding some more sawdust.
