Major issue Course Progress

We have been developing a commercial site based on this theme for some 6 months. We aboiut 2 weeks from going live and are doing a full up test with 3 testers working over everything before going live. We have discovered something that was fixed months ago that has come back again. The course progress bar in not working correctly. Step (1) When you go into a course and complete course units the course progress bar shows an accurate percentage complete. GOOD Step (2) When you go to Dashboard and view the course progress widget the percentage shown is correct. GOOD Step (3) (a) When you then go back into the course the previous completed units are remembered and shown correctly. GOOD Step (3) (b) However when you look at the precentage complete bar it shows Zero percent complete even though previously completed units are stored correctly. BAD Step (4) If you go back to the Dashboard the course complete widget shows Zero Percent. BAD Step (5) When you go back in the course the percentage is still Zero and the units complete form previous sessions are shown and stored correctly. Then if you complete futher units its shows these units as an incorrect percentage as if the other previously completed and stored units were never completed. BAD Step (6) You then go to dashboard and the course complete widget shows this incorrect percentage from the previous session. BAD Step (7) When you go back into the course again units completed form ALL previous sessions are shown and stored correctly but the course complete bar shows Zero We are experienced and professional Wordpress users so before bringing this bug to you we tried to resolve ourselves. (1) Disable Ajax. This did not solve the problem. (2) We deactivated events plugin without effect. (3) Made sure all plugins were up to date and once again no effect. (4) We have a test site seperate to our developement site with the bear bones WPLMS theme plugins installed without customizations or other activated plugins. On this site the same behaviour is observed proving no plugin conflicts. If you are having issues replicating this bug I can give you access to our bear bones WPLMS test site so you can see and replicate the behavour yourself.  I would have given you details hear but very very frustrating I cant see private setting and further more in my profile I cannot see any other way to raise a ticket arrrrrh While it is great to see the bugs in WPMS dramatically fall in recent months this is one that is very irritating to see as you guys have previosuly fixed this.
