csv output at coordinate points shifts when there are layers

[laurenebouaziz]

when testing the csv output at a specific coordinate for ustorelayerdepth (which contains data for the 4 layers), I noticed that the output does not come out as [0.0, 0.0, 0.0, 0.0] but rather as 0.0, 0.0, 0.0, 0.0 (without brackets) and therefore it shifts all subsequent output columns (which then do not match the header anymore).

In case the output is averaged over a map, the csv output includes the brackets [0.0, 0.0, 0.0, 0.0]
