Usually a restless BP indicates stress, but it doesn't look like her setup is an issue. Is she ever in her hides? If she is never in her hides, it may be that she doesn't find them secure enough (too big of entrance, too big in general). Often if I have a BP that is very active, I will give them a different hide, and then they will be in their hide all the time. What kind of hides are you using?
