Hi @isality!

Is this the query you sent to VM? Could you try following query instead:

WITH (
 allFilters = {instance="host", cpu="All",mode!~"(total|idle|user|system|wait|steal)"},
 cpu3Filters = {instance="host",cpu="cpu3",mode!~"(idle|user|system|wait|steal)"}
)

clamp_max( 
sum by (instance) (
  avg by (mode) (
   (clamp_max(rate(node_cpu{cpu3Filters}[5m]),1)) 
   or (clamp_max(irate(node_cpu{cpu3Filters}[5m]),1) *100) 
   or sum(avg_over_time(node_cpu_average{allFilters}[5m]))
)),100)

@isality, thanks for the bug report. The following minimal query reproduces it:

sum(a) or sum(b)

The bug should be fixed in the next release.

As for the original query, it looks really complicated and, as @hagen1778 already noted, it may be significantly simplified with CTE expressions supported by VictoriaMetrics. Read more about CTE and try them here.
