Gutters on metal building installed with no slope

Help I have gutters on a metal roofed commercial building that are holding water. The back of the gutters are attached to the under side of the metal roof overhang and the fronts are attached with 12" long hangers made of roofing metal ribs that lay over the roof rib and extend out to the inside lip of gutter front. This idea is very uniform but does not flow the final water to the two downspouts that are inset from the ends about 12' to 15'. There is 25' or 30' between the two downspouts. I don't see a way to create fall .
I just had to reattach the back in the middle section as it got overloaded due to one downspout being clogged. The gutter back pulled right off the screws that hang it from the roof metal.
I suppose the two downspouts cold be shimmed down and inch or so then have a custom shim at each mounting point.
Also wondering if a flowable leveling material could work to create Internal high points at the ends and the center. Thinking this would seal the leaks too.
