Habsburg Ruler Ladislas Postumus 1439 to 1457

Is this a bug? Everything I find on the web says this guy ruled only Hungary and Bohemia between those dates, not Austria.

I only noticed because I was writing an AAR that included the Duke of Austria in the 1450's and when I looked up Ladislas Postumus on the web the only references I could find were to the King of Hungary whilst Frederick V (HRE Frederick III) was listed as the ruler of Austria. So I went with Frederick as the ruler and Emperor in my story , was I wrong?

It's a bit complicated; well, after the break of Habsburg family in Leopoldine and Albertine branches (can't remember the date) Austria was divided among them. Albrecht II was the last descendant of Albertine line and Duke of Austria as Albrecht V while Frederick V (ruler of Styria) was the descendant of Leopoldine line along with his cousin Sigmund (ruler of Tyrol).
At the death of Albrecht, Frederick took control of Austria as "protector" of Ladislaus Postumus (Albrecht's son) but couldn't rule Hungary and Bohemia as nobility rebelled against him.
At Ladislaus death without heirs, Frederick was forced to give Austria to his brother Albrecht VI and Hungary and Bohemia went to Jagellonian son of the king of Poland. Eventually Albrecht VI died and Sigmund ceded his rights for Alsace and Swebia; thus Frederick realized the union of Habsburg lands under one ruler.
As Styria and Tyrol countries don't exist (unlike the EEP), I suggested that Ladislaus was removed and replaced with Frederick to make him Emperor after Albrecht II death.
