Buggy QAN page on PMM

I have requirement to add a node with custom node name. I executed the following commands:
sudo pmm-admin config --server-insecure-tls --server-url=‘https://mypmm:443’ generic Staging[1]

sudo pmm-admin add mysql Staging1 --query-source=perfschema --username=pmm --password=my_passwrd

But when I check node name from QAN page to see result of this nodes it gives me message:
" No queries available for this combination of filters in the selected time frame"

However, after refreshing page if I check results with service name it works fine.
Could you please help me to understand what could be the problem here.

PMM version 9.2.20


Hello, most probably it might be related to parentheses you have in node name. We need to reproduce it, but it’s what I have from the top of my mind.

Thank you @nurlan, after removing parentheses from the name the issue is resolved.
