Medical Logs? (In the app)

Anyone else noticed that you can't enter a diastolic blood pressure number lower than 90?? Mine is 75, so I can't log it.  
Also, why does the heart rate (for mom, not the baby's) only go as low as 90 bpm??  Mine is only around 68 - 85 bpm. So I can't log it either.... 
Is anyone else having this problem??
