Eneloop Pros don’t last as long as standard Eneloops. Depending how old they are, it’s possible they have aged enough that they won’t perform as well as standard ones. (Either lost capacity or high internal resistance.)
Or, maybe you got fakes? I’ve heard that it’s pretty easy to get fakes from Amazon, even if you’re buying from a reputable vendor. In most cases, the same goods from multiple vendors are lumped into the same Amazon bin, so you can be getting goods from any vendor that sells them.
