There was a publishing hiatus between #9 (February 1974) and #10 (September-October 1974). The Supergirl feature was continued from Adventure Comics (DC, 1938 series) #424, and continued in The Superman Family (DC, 1974 series) #165, June-July 1974, which was a revamp not reflected in the later #10.
