Pathauto, FeedAPI and blog entries

I have the following definitions:

* in Blog path settings:

[user-raw]/blog

* in Node path settings / Pattern for all Blog entry paths:

[author-name-raw]/blog/[title-raw]

(copied and pasted, so there are no spelling mistakes).

Blog path settings work fine. Then, when I create new blog entry using Create content / Blog entry, everything works fine too. Example path:

pendragon/blog/test

However, I am also using FeedAPI to fetch RSS feeds from other sites, and save fetched RSS items as blog entries.

And here the problem starts, as all new created blog items have path:

blog/test

(without username at the beginning).

Tried deleting all existing URL aliases using both URL aliases / Delete aliases, and directly from the database. Did not help. After bulk regenerating all node aliases, blog aliases are incorrect again.

The same applies to newly created items.

Any ideas?
