Phantom 4 Series - Battery Charging Hub Not Working

[thesinfull1]

I had to send my phantom pro 4 back to dji for repair/replacement so while waiting for it's return, I swapped the charging hub to "storage". I thought this was what I should do instead of allowing my other 2 batteries stay charged or allow them to completely discharge. I received my new drone, swapped the charging hub back to "charge" setting, but unforfunately they batteried will not charge. Am I doing something wrong? The indicating lights stay at yellow never giving an indication that they are charging and when I try powering up the batteries, they just turn themselves back off.
