I'm not sure if this appropriate for 'How To' - but I couldn't find another outlet to ask this question which I presume is either a bug or user error...so here I am, asking 'How to' fix this issue. 
I have a series of reoccurring monthly projects that are created from a blueprint on reconciling monthly expenses. My project is set with a 'progress' measured by 'Completed Tasks' and has 7 tasks to complete each month. This works seamlessly most times - but suddenly I'm encountering some random duplicates of this blueprint have a 'Progress' of 100% - even though all the tasks in the project are 'pending'.
I double-checked the progress measurement is set correctly, and even tried 'completing' and changing task statuses back to pending to see if it changed the measurement - but it never changes from 100%. It doesn't do this on all projects created from this blueprint - only a few (seemingly) random ones.
Am I doing something wrong or missing something - or is this a bug? Some screenshots of what's happening below:
