It's not such a surprise that Jenna is leaving as she has just been an extra in the café for ages now, not contributing much. Having said that, I did enjoy her scenes with Andrea in the hospital. Can't wait for her to discover "Andrea's secret". 
Agee with ewoodie and Maria_Robinson that she could have been an ideal gym receptionist and maybe her character could have been explored a bit more. With Kal's extended family arriving soon maybe she could've hooked up with his daughter or become friends with her. Jenna has had no romantic interests since Sophie and it seems strange she hasn't explored this further.
I get the impression the writers haven't had many ideas of what direction to send her.
