Remembering scores in conversation transcipts doesn't seem to work right

The newly introduced feature - remembering marks in conversation transcripts - doesn't seem to work right at least in Level 2. I haven't checked on level 3.
The scores seem to be remembered correctly on the day, but if I go back to older sessions I find that there are many low scores when I know that they were nearly all 100% when I did the section.
 

Hi sfpugh, 

I am sorry to hear about the inconvenience; do you continue to have issues with the scores given in the lesson and its memory? Please let us know and we can check with our IT Team for review. 

Kind Regards!
 

The scores are working correctly now. The problem arose in the early days when there was an attempt to link scores in tests with those in the lessons. Since feature was removed it works correctly.
