It seems that all your DOC cals are already allocated, now if you check all documents and none seems to be allocated, it could be that you deleted previous documents that you had document CALs allocated. in the "user document" tab within the QMC, do you see document at the bottom of the list with all CAPS? (ex. SALEOFLASTYEAR.QVW). To recover those CALs, there are different options to recover them.
