Recharge rate cap or bug in Mids'?

I was just working on a possible high damage build (fiery melee/super reflexes scrapper) in Mids' Hero and Villain Designer today, and I've noticed that after the first 5 Luck of the Gambler: Recharge Speed enhancements, Mids' stopped counting any more of the +7.5% recharge speed enhancements. This is a bit confusing, as super reflexes alone has slots for 6 of these, and being that this is a global enhancement it's easy to stack in a few more via power pool powers.

So, my question is, is there an actual in-game cap on how many of these recharge speed enhancements I can get a benefit from, or is there just a bug in the hero designer?

This is rather important to my build, as it makes a difference (after a ton of rare and costly IO's (no super rares though)) of having either a 68.8% recharge speed boost, or a 98.8% recharge speed boost. If the former is the case, in my opinion I'd be better off just taking haste on a different build, as you can easily have that up the majority of the time for an additional 70% recharge speed boost, on top of whatever other IO set bonuses you get.

Does anybody have any ideas about this?

Simply put, you've just run afoul of the rule of 5. In short, you can't have more than 5 of any given set bonus, any beyond that are wasted. So you can't have more than 5 LoTG 7.5% bonuses, more than 5 regular 7.5% recharge bonuses, more than 5 5% recharge bonuses, etc, etc. This also applies to all other types of set bonuses - HP, recovery, whatever.

You can only have up to 5 of the same named set bonus; the 6th onward provide no additional benefit.

In Mids' click "View Active Sets" and it highlights in red any set bonuses that are above the cap.

Bah, so much for that build. Thanks for the info though, I'd have hated to have bought 6+ of those LotG sets only to find out then that it doesn't work.
