This is not the same problem that you have now. Now the problem comes from "Adjust" fields, but I don't really know how you got them. In your previous project I can find this situation:

In your current project I see this:

Even these 2 problems are not exactly the same. What do you want to do in "Adjust"?
By the way, to fix the problem in the previous projects, open Custom (price level), fix or remove the Adjust field and then go back to the original setting. The thing is that each block has more input parameters than what you can see, some are invisible, but still there.
To fix the current project just remove that . symbol after *2
