Forgive me, I don't know any of the lingo as to what the upgrades are called in terms of what you all call them in shorthand but...
I have the Reman shields (which turn your ship green in places). I've noticed that when I remove some engineering and science consoles that boost shield strength and efficiency, the shield strength and recharge rate stays the same. When I do the same to a standard shield, the strength and other attributes go down by levels of magnitude.
Do I need those science and engineering upgrades or can I free up those slots for something else?
I think the regen rate stat is bugged somehow, it never shows up properly or even at all for most of the shields I try to use when I am in orbit. It will only display for certain shields like the Jem'Hadar or Borg, if I used anything anything else it doesn't even show a recharge rate under my ship panel.
