How to do the workaround

1 - Step:

Go to the directory below.

cd /usr/local/omk/templates/nmis/nodes/resources/

Then use the vim editor in Linux or another of your preference.

vim  node_resource_table.html.ep

According to figure 4, you need to go on lines 84, 88, and 109. Then, remove this portion of the code on the line:  class=> "text-decoration-none”, which is highlighted in red in each line that needs it.
