The four 10U chassis account for 40U worth of space. 0U devices do not contribute to the sum of utilized space (this is literally a SUM() operation which adds 0 for each 0U device). However, it does include the height of non-0U devices which have been assigned to the rack without a position, e.g. the Dell M1000e switch you have defined. What is the defined height of that device type?

It seems that the extra U space can be attributed to the non-racked devices listed. I'm going to close this out but feel free to respond if you find otherwise.

Hi @jeremystretch the dell m1000e switch is 0U. I've went through all the devices and everything that is not the M1000e is set to 0U.
