Tuat "Victory" building

[Zett]

In my Makedonian Campaign I captured Tuat and in the city was a building called "Victory".
From a google search i found out that it is a marker similar like the ones in Terhazza.

Now my Question: Why can i build a type 1 gov there? Is it related to the marker or is it a bug?



I also used the Forumsearch and found a topic related to my problem https://forums.totalwar.org/vb/showthread.php?t=103892 , but the question (last post) wasn't answered.
