Can you post a picture of the leveler control panel? There are a lot of different models and a lot of changes over the years.
You did have the engine running and the parking brake set when you tried the second time, right? Our LCI levelers require that.
We never use auto level because it just raises the coach too high, even after I recalibrated it, and it bounces the coach too much as it does its thing. We always use Manual.
Lower the fronts until they just touch, lower them more if needed to get level front-to-rear, then lower the rears until they just touch. Then do the left-right part.
One of the best $150 I spent was for a LevelMatePRO. It's an electronic level. The box mounts inside a cabinet on an outside wall and has a display on my phone. It shows how many inches of blocks we would need on each corner to get level.
When we arrive at a site we look at the LevelMatePRO display and reposition the motorhome to get as level as possible. Since buying that thing I've never had to put blocks under the wheels. One place we were showed we needed 10" of blocks under the rear tires. We moved the motorhome slightly and got almost level but we sure could not tell there was that much of a difference just by looking at the site.
