Cabinet/Oven/Microwave/Gap between shelf/oven

Hello everyone,

I have a problem installing a microwave and oven in a Faktum cabinet. I used holes 17 and 36 as specified, but when I install them this way, there is a gap between the two that is not insignificant. Also, the black bottom rail of the microwave doesn't really cover it, and besides a gap between the shelf and the oven, there is also the white shelf that is clearly visible. Visually, not exactly a highlight.

Does anyone know this problem? I cannot place the shelf at 35 because then the oven no longer fits in between.

Here is a picture of it:

Thanks to you all!!

Hello the three???,
is the floor resting on a shelf board or a so-called construction floor? The shelf board has semi-circular holes on the side, the other has holes with white plastic fittings. If it is on a shelf board, I would put a second one on top. If it is a construction floor, I would replace it with a shelf board. With the latter, you get about 1 cm higher.

There are two different types of ground beams in reinforced soil. Have you tried both?
