S Health won't let me manually input seconds for my runs

[AC Question]

I never run with my phone, so therefore I always record my run times manually. Up until yesterday, I could manually input my run time down to the second. All of the sudden, now I can't. S Health is only using an hour:minute format and I can't seem to change it. For running, at least to me, seconds actually count and I'd really like to be able to input them. Any one have suggestions? Appreciate it in advance.
