Unify behavior for CPU and RAM columns when no data is available

[adameat]

Currently, the behavior for the CPU and RAM columns is inconsistent when no data is available. As seen in the attached image, the RAM column displays "no data" when information is missing, but the CPU column shows a dash (–). To improve UX, make the behavior for the CPU column consistent with the RAM column (for example, display "no data" instead of a dash when CPU information is missing).

I would suggest do display dash instead of "no data"
