3DEXPERIENCE - Power spectral density assignment to load

Hi, I am having trouble with creating a tabular of different frequencies and energy levels in the PSD-table(only allowed one freq)

In addition to this, when i create my load, i do not have the option to choose the PSD-table i created.

As a result of this, the software complains that the load does not have a psd assigned..

Anynone run into this problem?
