Ok, first things first. Which software? If you
don't include all the information it makes it really hard to help.

This is most probably a notational error:
43.24º is 43º14' and 86.24º is 86º14'
In each case the first number is in decimal
degrees and the second is in degrees and
minutes. In general, you need to understand what
units the software is displaying and realize that
looking at the same location in two different
APRS clients may display the location in
different representations. Some APRS clients have
facilities to convert between the different
representations. The most "normal" representation
in APRS is degrees minutes and decimal minutes.
Note that UI-View uses a confusing representation
with two decimal points but it really uses
degrees, minutes and decimal minutes.
Your main options for displaying latitude and longitude are:
Degrees, Minutes, Seconds - Dº M' S"
Degrees, Minutes, Decimal Minutes - Dº M.m'
Degrees, Decimal Minutes - D.Mº
For conversion purposes:
60 minutes is one degree, 60 seconds is one minute
Hope this helps
