Scripted maintenance period does not properly show in maintenance list

[waardd]

When we create a maintenance period with a script (see further down for the script) the periods are not showing in the right way in the list.
See picture below, it shows several pages but all are empty


I am wondering if its a bug in Zabbix where we for instance use characters that are forbidden or something.... or is it the json calls in the script?

The script we use is as following:

#!/bin/bash

###################################################################
#Script Name    : zabbix_json_tst.sh
#Description    : Set the maintenance period for a zabbix host-group
#Author         : Danny de Waard
#Email          : [email protected]
