Question overshooting of covered gutter system

I have a covered gutter system to protect the gutter from clogged by leaves.

I found the basement is wet, which pointing me to find the problem in the covered gutter system.

The water overshoots to the ground rather than into the gutter system, which happens even during a moderate rain when I watch in the rain.

My questionare are
Is overshooting a common problem for covered gutter system?
What causes the problem? Not instored properly, or deformed after instoration when the house was build in 2004.
Is it easy to fix by myself or a repairman?

I have tried a couple gutter guards and none worked well for me. Fancy metal guards only worked with slow gentle rain. Worst was the one where the water flows over the guard and is supposed to follow a rounded lip back into the gutter. With anything more than a light rain that guard might as well have been a ski jump for the water. Best was cheap plastic mesh strip that covered the gutter but when installed the mesh formed an arch which trapped leaves right at the roof's edge. Currently my gutters are now "commando" with no guards.

My parents have gutter helmet and no water infiltration issues but I don't know if that's due to grading or if all of the water is actually making it into the gutter, I've never watched to see.

I've always suspected those gutter guards probably kept the rain out at least as effectively as they kept the leaves and debris out. My wife keeps insisting we get them, but I don't know a single person who has used them and recommends them. I hate doing high work of any kind (vertigo), but there's no substitute for cleaning out your gutters and downspouts at least twice a year. A good pressure washer is a big help.
