Mine also says unlimited.

I did notice, however, that your Island Rank is 0, which happens when it's taking some time to "load" your stats, so it may be that "Max Beds" shows up as 500 when it's still "loading." This could be caused by the necessity of some number, even if it's a high number, in order for the game to properly "process" the whole beds occuppied vs. max beds thing. So unlimited may actually be 500, but the developers thought that number would be plenty high enough to hold all the monsters you could fit on the island (which most likely would have been tested by math or actual game testing). I've known other games to employ this method, because otherwise it might glitch the system or something of that nature. :)
