Hello,
For my corpus, I cleaned the list of authors and when I tried to re-index the list I got an issue. The indexed list gives the columns (Stem, main form, forms) as I prepared it in Open Office, but the frequency is 0 for all entries. During the data parsing I already read a ‘debug’:

It seems that the generated database does not contain any table, did you select the correct source for your dataset?

I hope someone can advice me. Thank you!
Best,
Renée
