Format of multi-selected values in view are quite weird. How to fix this format?

[TobiasLorenzHDM]

These values are depicted in my view:
NTONDATA:{"actions":[{"associate":true,"guid":"378e9aed-e122-ed11-b83d-000d3ab32811"},{"associate":true,"guid":"9be4c7f6-e122-ed11-b83d-000d3a65303f"}],"len":"hdm_sma_std_lehrgang","ida":"hdm_sma_std_lehrgangid","na":"hdm_sma_std_lehrgangsname","re":"hdm_techniker_hdm_sma_std_lehrgang","rn":"hdm_Techniker_hdm_sma_std_Lehrgang"}

This is how the lookup looks like in the form:

Any help is much appreciated, I also can provide more information if needed/ desired.
