New date formatting in "RUNPERIOD" section of idf file? fileupdate does not deal with this

edit

I have a v8.7 idf file the RUNPERIOD section looks like this:

!-   ===========  ALL OBJECTS IN CLASS: RUNPERIOD ===========

  RunPeriod,
    ,                        !- Name
    1,                       !- Begin Month
    1,                       !- Begin Day of Month
    12,                      !- End Month
    31,                      !- End Day of Month
    MONDAY,                  !- Day of Week for Start Day
    No,                      !- Use Weather File Holidays and Special Days
    No,                      !- Use Weather File Daylight Saving Period
    No,                      !- Apply Weekend Holiday Rule
    Yes,                     !- Use Weather File Rain Indicators
    Yes,                     !- Use Weather File Snow Indicators
    1.0000;                  !- Number of Times Runperiod to be Repeated

When I run fileconvert to upgrade to v9.0 this is what happens:

!-   ===========  ALL OBJECTS IN CLASS: RUNPERIOD ===========

  RunPeriod,
    ,                        !- Name
    1,                       !- Begin Month
    1,                       !- Begin Day of Month
    12,                        !- Begin Year
    31,                      !- End Month
    31,                      !- End Day of Month
    ,                        !- End Year
    MONDAY,                  !- Day of Week for Start Day
    No,                      !- Use Weather File Holidays and Special Days
    No,                      !- Use Weather File Daylight Saving Period
    No,                      !- Apply Weekend Holiday Rule
    Yes,                     !- Use Weather File Rain Indicators
    Yes,                     !- Use Weather File Snow Indicators
    ;                        !- Treat Weather as Actual

When I create a new file in E+ 9.01 RUNPERIOD looks like this (NOTE: I had to put in the 2019 date):

!-   ===========  ALL OBJECTS IN CLASS: RUNPERIOD ===========

RunPeriod,
    1,                       !- Name
    1,                       !- Begin Month
    1,                       !- Begin Day of Month
    2019,                    !- Begin Year
    12,                      !- End Month
    31,                      !- End Day of Month
    2019,                    !- End Year
    Monday,                  !- Day of Week for Start Day
    Yes,                     !- Use Weather File Holidays and Special Days
    Yes,                     !- Use Weather File Daylight Saving Period
    No,                      !- Apply Weekend Holiday Rule
    Yes,                     !- Use Weather File Rain Indicators
    Yes,                     !- Use Weather File Snow Indicators
    No;                      !- Treat Weather as Actual

There seems to be a fileupdate error?
