If I look at your question, it seems that one of your polygon is selected. Make sure that you unselect it in order to run on all features.

Also, I recommed to make copy of your FID field in a new column and use this column as a zone field. FID could change when you edit or export data. This can be done with the field calculator.

Another thing to watch is the actual resolution used by arcgis in the analysis. Make sure to fix i to 30 meter in the environment variables of your tool.

Finally, create buffer for all polygons in different shapefiles (dissolve option at "none") and run them one after the other (right click on the tool and select "batch", because overlapping polygon are not wel managed by zonal statistics (which internally converts into raster, which means that only one value can exist for a given pixel.
