Nope, it’s not only yours. I could reproduce it as well.
And same goes for the other bugs you reported (#17-19). Though #17 may have something to do with the fact that Cave of Gerfrex is a WoG map, so some of its elements might not be fully supported by VCMI.

#20 Mouse click in the scroll area in the list of available Scenarios, does not work as page up/down like in H3 but it really takes us to that part of the whole list. It’s not really a bug, just different behavior. I’m not sure if it needs changing or not.
#21 ‘H’ key on Adventure map centers on the 1st hero in the list (even if he’s out of movement points). Instead, it should select/center the next hero in the list with movement points left. That also means that if no hero has movement points left, H should do nothing.
[size=75]FYI - For centering on the currently selected hero, there’s another hotkey - Spacebar - which however has “revisit location” as primary function (so it just centers only when hero is not at any location that can be visited). That’s already implemented and working fine. For pure “center hero” purposes H3 had no dedicated shortcut, that’s why I suggested in the “Missing features” thread to assign NumPad “5” for it - when the other NumPad keys will be implemented for hero movement.[/size]
#22 Leave Guards window graphic glitch :
[size=75](luckily the above bug had me testing ‘revisit locations’ hotkey:)[/size]
#23 Hero screen: Hovering over unselected creatures displays subtitle “Select xxx (in garrison)”. It should only say “Select xxx”
#24 Stone Golems make the Iron Golem sound when walking in battle, and vice-versa.
#25 Also Split Creature Stack button is missing from the window (though probably you already knew that) 
#26 ‘T’ hotkey opens now Marketplace window, however Trading Post doesn’t work anymore.
