This is because grass (and other weed seeds) can germinate and grow within the mulch itself, and grasses can send roots into the mulch and start to grow. If you use landscape fabric (or even newspaper or cardboard) under the mulch, it will kill off the existing grass.
First, you could rake off the mulch you applied, lay 4-6 sheets of newspaper over all of the grass, and spread the mulch over it all. The newspaper layer will smother the grass and eventually break down naturally. The other option is a chemical one; spot-spray the grass with a herbicide like Roundup.
Similarly, can you put bark over grass? Simply cover the area with a weed suppressant membrane – that will save you a lot of work over time. Then put a nice thick layer of bark over the top of it.
