Why is this surprising?  For example, installing 2.3b1 does not uninstall
2.2.  Did you uninstall 2.2?

Whether one or more of those should have gotten overwritten depends on
things you haven't told us, such as whether you clicked on the Advanced
options button when installing, and, if so, whether you did an Admin or
Non-Admin install, and whether you chose to associate file extensions or

Sorry, don't know what that means.

Not enough info here to guess whether there's a bug.
