Interpolate to Timestep in EnergyPlus 8.9

edit

Lately I was upgrading to OS 2.5.0 which uses E+ 8.9. When I try to run one of my models which use to run smoothly in OS 2.4.0 it failed with the following massage:

Program Version,EnergyPlus, Version 8.9.0-eba93e8e1b, YMD=2018.05.07 20:08,
   ** Severe  ** <root>[Schedule:Day:Interval][2BHDO Default][interpolate_to_timestep] - "yes" - Failed to match against any enum values.
   **  Fatal  ** Errors occurred on processing input file. Preceding condition(s) cause termination.

I am changing the Schedule:Day:Interval's interpolate_to_timestep property to yes with a measure I wrote since OS will not expose it.

Since it is a Yes or yes enum issue I would guess it will affect many other things. Has anyone experienced such a warning?
