Your soil calcium is very high but possibly you have a lot of limestone in your area causing this. It will not all be available to plants.

I also noticed that your %OM is 27% which is very high and means that there is lots of material that is not broken down yet. This decomposition process can cause certain nutrients to become unavailable to roots.

Average %OM in my area is 4% but mine is 8-10% and I don't want to go much higher than that.

I checked my soil test report and my Calcium is even higher than yours at 7257 PPA. According to Penn State the optimum range is 5000-5600 PPA so your is not unduly high at 4850
