Yes, it is the search function that is causing you the issue. With your previous function you will try to use an external csv file. A detailed workaround of the same can be seen in a previous post (here you will see the values being pulled from a csv values using the search function):
As a work around maybe you could re-design your xlsform as shared below. This should solve your issue. Note, using the approach shared below, you will not need to use the external csv file as the choices are already laid in the choices sheet.
Edited xlsform
