Different variable names when downloading as SPSS through API

Hi,
I use the qualtrics API to regularly download data from large surveys.
When downloading the data (as spss files) through the API variable names that I have assigned through the survey editor are not appearing in SPSS as i named them and instead are getting 'qualtrics style names' (like A_xx.xx).
When i download the data directly through the export data option on the web portal the names do appear correctly in SPSS.
I am pasting below part of the python code i am running to access the API.
This is a major problem for us, please help!
thanks,
Eli
