We are using On-Premise
Nintex workflow version: 5.2.6.0
SharePoint: SharePoint Server 2019

Nintex workflow progress was supposed to show completed actions in green color and on-going action in yellow color. We found that in case of workflow issue some of the workflows, workflow progress diagram is showing unactioned actions too in green color, so we lost the trust on workflow progress diagrams.

Can someone help us with what could be the cause of this issue please? Thanks
