Import annotation from CSV works incorrect in one case

An error occurs when trying to import annotation from a file marking name column, start position column, end position column and length column.

The file like:
"Group","Name","Start","End","Length","Complementary","Gene","desc","property","prop1","prop2"
"test","test01","1","400","400","no","tEs01","unknown funtion","blablabla","",""
"test","test02","3660108","3771020","110913","yes","","","","kobietghiginua","addsomethinghere"
