Eurostat - Problem with retail trade series

I use a loop to download data for retail trade for different countries. The database is EUROSTAT (ei-isrt-m) and the series are the following:


In the case of Spain, I get empty 0x1 series in Matlab even though the slug exists. Apparently there is a problem with the second column of data where comments about the nature of data (p-provisional, e-estimate,…) are shown. In countries/series where there are only some of these remarks, the download is successful; however, in the case of Spain the remarks column is full throughout the date span of the series and the script does not seem to be able to decide on which column to download.

Can you look at this? Thank you!
