problem on ballgown

Question

[mo.ghasemi717]

Hi everyone recently i analyzed my data using stringtie and ballgown, but in the final step, the column of gene name is empty and the column of geneiD in almost all of rows is showing MSTRG. what does it mean? and how can I find my gene names ??

my result:

       geneNames     geneIDs    feature     id
3657           .     MSTRG.1 transcript   3657
