It's not the springs. It's the mag inner sitting too far out of the feed tube allowing the bb retention nub to close. If you pull on the front bottom of the mag they will feed again as this pushes the nub back open. You need to shim your mag inners higher at the rear, and securely peg them in place.
I had to do the same thing with my LCT midcaps. And the review I wrote also mentions this and has the shimming solution. If that solution doesn't make sense just PM me, I had another guy asking about it a few months ago in PM's and I did him a more detailed explanation of the modification.
You need to inspect you mags first before you take them to bits.
The part I refer to as rollovers (blue) are the sides of the metal part of the mag where the mag comes up and over the feed nozzle. The goal is to get the top of the feed tube (purple) to be in line with the rollovers - as show by the magazine top line (red). See image.
In order to get the feed nozzle to be inline with those rollovers you are going to have to make a few modifications to both parts of the mag.
The plastic internal bit needs a chamfer (Angled edge) filing onto the leading edge of the magazine (orange second image).
The metal tang (green) needs bending out a little to allow the plastic parts to sit higher.
Once you have the feed nozzle in line with the magazine top line doing these actions you will then need to shim the plastic parts into place.
I made pegs/wedges. All they are is plastic that has been shaped to hold the plastic part of the magazine tight to the magazine top line. Those wedges are long enough that the magazine base plate holds them in and up. Stopping the feed tube falling away from the hop unit in the gun.
I had some 5mm x 6mm plasticard lengths for building models. The business end got whittled to a taper.
