Required mods of Composite bows not being required

I tried, on those two versions and the latest autobuild in 35e mode and RSRD, to buy a Shortbow (Composite) (and, for the heck of it, Shortbow (Composite +0)), or their Longbow equivalents, and the mods were not required as they should be. I thought for sure I had used this feature before and was required to do the mods, so I am not sure what changed and when.

Required customization of at least some items, like Gem and Art, did generate the pop-up window about the required customization.
