Undefined index: alpha, omega and omega_kickstart in theme_update_report

Hi,
Can some help?
After created an omega kickstart subtheme, by copying commerce kickstart, passed and renamed it in theme folder under /sites, and made necessary changes to mysubtheme (in mysbtheme.info, template.php, css, scss and js fliles) to rename all the files found at /sites/all/themes/mysubthemename, to include mysubthemename. I have enabled mysubtheme and it seems to work fine.
But I'm getting the folowing error message in availabe update page:

Notice: Undefined index: alpha in theme_update_report() (line 202 of /home/mysite/public_html/modules/update/update.report.inc).
Notice: Undefined index: omega in theme_update_report() (line 202 of /home/mysite/public_html/modules/update/update.report.inc).
