Top hosts doesn't show correct information when Column field has multiple possible values with same item name

Steps to reproduce:

There are two Templates, named Uptime SNMP Puro and Template Juniper Uptime. Both have an item named Uptime. Depending on the device and how uptime is calculated, one of these Templates are chosen.

DEVICE A and DEVICE B have linked Template Juniper Uptime, while DEVICE C has linked to it Template Uptime SNMP Puro.

Now, I'd like to create a dashboard type Top hosts to show all the devices ordered by its respective Uptime. The configuration below is applied. Uptime item is chosen:

But the result is: only DEVICE A and DEVICE B are shown, which ones have linked Template Juniper Uptime. But DEVICE C should be presented as well, since it has an item named Uptime.

If an item that is commom to all devices and use the same Template is selected, like ICMP ping, then all devices are presented.

Expected:
Regardless of the Template a device is linked, if it has an item named Uptime, it should be presented on Top hosts.
