Just curious if this is anything to worry about or perhaps I did something wrong?

On a test site, I upgraded from 1.3.9h to 1.5.0. After choosing Upgrade Database, I received the following error:

ATTENTION: Problems Found

NOTE: Skipped upgrade statements: 4

At the bottom of screen the following appears:

SKIPPED: Cannot drop index page_accessed on table admin_activity_log because it does not exist.
SKIPPED: Cannot drop index access_date on table admin_activity_log because it does not exist.
SKIPPED: Cannot add index idx_page_accessed_zen to table admin_activity_log because it already exists.
SKIPPED: Cannot add index idx_access_date_zen to table admin_activity_log because it already exists.
