Moon's Graden

My Brachypelma Smithi just molted but not all the old skin has come
off of her abdomen. There was a piece of her carapace still stuck
there that I was able to easily remove with tweezers (pulling a little
of the old skin with it) about 5 days after he molt. However, much of
the back end of her abdomen (including her spinnerets) still appears
to be wrapped in the old skin. Is this something I should be concerned
about?

Thanks in advance...

Update: The old skin has worked its way off (or she was able to do so
herself). All is well...
