I am using a program called My Heritage Family Tree Builder to create a GEDCOM file of my family tree. Upon uplodaing the file I found that a series of numbers and letters are displayed on the rootsweb page that I don't want there. How do I delete this excess data?

This is a sample of what it looks like on the page:
Birth:
_UID: A2E84ADC-3D7B-41E1-A3F5-C1C7375B4592
RIN: MH:IF137 ABT 1843
Death:
_UID: 988E2739-6FC1-4D92-9718-C87A4D10F40C
RIN: MH:IF138 1903
RIN: MH:I69
_UID: E781CC53-CF36-4454-B517-1C801ADBD899

Thanks,
