What's up with the maxed out? - Kalinka Optics KOM 6x42 Illuminated Modern 1000m Reticle Rifle Scope w/ Focus

I ordered this because it comes with AK side mount. Before they process this item, they need to go through some back ground check with me and it took a while. After they confirmed it, it took another 2 weeks for them to order the item and ship it, then another week for it to arrive. The whole process was dragging and I wasn't very happy about it.

Finally, the scope arrives, I installed it on my AK with no problem, made sure that I followed all the instructions and was so excited to zero it in in range. What happened was that I maxed out my elevation and the cross hair still six inch above the POI.

I talked with Kalinka and Opticplanet, they did not provide sufficient support for problem solving. I don't know what else I can do without breaking the scope apart. So I think I will have to return it and pay for the return shipping in the end. It was not a good experience owning a Kalinka nor shopping with Opticplanet.
