Hello, I have a problem when I tried to import a .idf file to OpenStudio. Here are the details about the error.

The collection is INVALID at strictness level 'Draft', because of the errors:
Field      level data error of type DataType          .
Error is in an object of type 'RunPeriod', named 'Run Period 1', in field 5.
Additional information about the error type: field-level data is of an incorrect type.
Field      level data error of type NumericBound      .
Error is in an object of type 'RunPeriod', named 'Run Period 1', in field 4.
Additional information about the error type: numeric data violates a min or max bound.

Is this text referring to a syntax error? Here is the RunPeriod text part of the .idf file.

RunPeriod,
    Run Period 1,            !- 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,                       !- Number of Times RunPeriod to be Repeated
    ,                        !- Increment Day of Week on repeat
    2018;                    !- Start Year

I have checked the object RunPeriod in my .idf file and it doesn't make sense to me because the fields 4 and 5 were already filled in correctly (or have I mistaken?). The current .idf file and EnergyPlus version that I am using are 8.9. Could you tell me how I should tackle this problem or if you have any solution? I have tried to solve it but I couldn't find any solution so I am asking for your help. If you need additional information to understand the problem please tell me. Thank you in advance.
