Cider Radiance Bug?

Hoping someone has some insight on this. I have been playing local co-op with Galandra and Cider. When we die and are resurrected, only Galandra's radiance gets subtracted and added to the radiance levels. Cider's radiance seems to be glitched at 3000 radiance (no matter what it was during the run), and it does not subtract, and does not add to the radiance levels. Her life bar is also stuck at not quite 100%. (But when we leave that area and start a new run, the radiance and life reset, only to return to the 3000/not quite 100% when we die again.)

Has anyone encountered this and know what's going on/how to fix it? Thanks for any thoughts. Just started this week and am having a blast otherwise.
