How to fix cropped labels?

Quick question, how do I get the full name of the values instead of cropped “VALUE…” ?

Here it is my current challenge, as you can see some server names are showing up correctly, while others for having a few extra characters are shown as “SERVER-0…”

My query just shows the server name, available disk space, and its total disk size, nothing more but some servers are shown with the “…” - and I can’t find anywhere an option to define the length or width for the bar gauge panel, is there anything to fix this issue?
