query for data "-1" in FND_PROFILE_OPTION_VALUES

Hi experts,

I have a query about the data "-1" in FND_PROFILE_OPTION_VALUES.

How can we check the profile value if the LEVEL_VALUE and LEVEL_VALUE_APPLICATION_ID  has "-1" in FND_PROFILE_OPTION_VALUES table using the form screen?

It looks these values are old data, and just remains for reference(history),

We do not know how can we determine if these are necessary or not, and also want to know how to check them using form screen.

Doesn't need to consider these values?

For example)

USER_PROFILE_OPTION_NAME   LEVEL_ID    LEVEL_VALUE    PROFILE_OPTION_VALUE               LEVEL_VALUE_APPLICATION_ID   LEVEL_VALUE2
