I can see 2 potential issues on a re-run:
1) If the tab is active we are hitting this part of code 
https://github.com/apache/hop/blob/167ed93e5af748c219d0b453a62d1afd42ff47f7/ui/src/main/java/org/apache/hop/ui/hopgui/file/pipeline/delegates/HopGuiPipelineGridDelegate.java#L123-L127

I think startRefreshMetricsTimer() should be called here too

The second bit is the actual timer itself. When execution a second time is 
seems the pipeline is still in the isFinished() or isStopped() state. I am 
guessing we are hitting this code before the states have been updated for the 
re-run this is causing this block to trigger
https://github.com/apache/hop/blob/167ed93e5af748c219d0b453a62d1afd42ff47f7/ui/src/main/java/org/apache/hop/ui/hopgui/file/pipeline/delegates/HopGuiPipelineGridDelegate.java#L277-L280

And the timer will be stopped 1 second after start (this is why we are seeing 
some metrics)
