[GRASS-user] Renaming a column changes the Data lengths

[Aldo CLERICI]

Dear all,
I'm having a little problem in changing the name of a column since the old versions of WinGRASS 7.0.x and it also continues in the latest version 7.4.0.
a) Made a copy of roads (in Spearfish) named roads_copia
b) With Show attribute data  Fig.1 the columns are correctly displayed.
c) With Manage tables > Add column a column named larghezza has been added Fig.2
d) The column is correctly inserted Fig.3
e)  With Rename column the column name has been changed in ampiezza (fig.4)
f) The Data lengths are changed as follows Fig.5.
Something wrong?
Thanks to everybody
Aldo Clerici
