Configuration problem with LEDs in the corner

Hi, i had a sk9822 stripe, cutted it and soldered it together so i can also have LEDs in the corners. Now i have the following problem: the layout in hyperion shows me the LEDs a bit wierd and i am not sure if this has some negative impact.

when i hover over the LEDs in the corners, they appear to be over each other, but in reallife, they are not.

even worse... my LED strip starts left bottom with first LED and then goes to top left (about LED 50), moves on from top left to top right and then from top right to right bottom. can i somehow configure that? i really dont want to remove the stripe again

i was able to set the position in the UI (input position), now its correct.
and i guess that it looks like a little matrix in the corners is just a display error
