Error when dealing with integer / radio button

[MattMuffin]

The error appears both when using PdfWrapper and FromWrapper, but with a different behavior.

Here is the test pdf file: https://www.cdc.gov/infectioncontrol/pdf/icar/IPC-demo-LTC-508.pdf

Loading the file shows this in the console:

Ignoring wrong pointing object 14 0 (offset 0)
Ignoring wrong pointing object 89 0 (offset 0)

EDIT: this could be the issue: https://github.com/py-pdf/pypdf/issues/2326

Calling the schema method:

pdf_form_schema = PdfWrapper("IPC-demo-LTC-508.pdf").schema

shows that the field "S1 GF 7" is of type "integer" (a radio button), with a maximum value of 2.

Problem 1: why is the maximum 2 when there are clearly 4 possible options? Starting with 0 = "Accute", 1 = "Long-term" , 2 = "Outpatient", but setting 3 = "Other" does nothing.

Problem 2: using FormWrapper setting the field "S1 GF 7" to any integer fails with the following message:

    return dict.__getitem__(self, key).get_object()
KeyError: '/D'

Problem 3: using FormWrapper: setting the field "S1 GF 7" to a string, like '0', always checks the option "Other".

Problem 4: using PdfWrapper: setting the field "S1 GF 7" to a string does nothing (soft fail?); setting the field "S1 GF 7" to an integer between 0 and 2 checks the appropriate field. I have not found a way to check the "Other" field option. I was expecting the same behavior using string as FormWrapper.
