Problem with Selecting Options within Drop down menu

Hi, i'm assigned with a task to select a web automation tool
for our company and currently evaluating Telerik Test Studio.

I recorded a web test using test studio and during the recording
there was a scenario where i had to select an option from a drop 
down menu. While recording, I was able to select any option within 
that menu and proceed with the recording.
But the problem came up when running the recoreded test. The 
option i selected while recording was not selected again when i ran the 
test.

Whly is this happening?

I was trying to record the usual activity flow of an usecase in our
application and encountered this problem.
