Sudden decrease in Ratings 7.2 - 6.0 (No Irregular Voting/Rating Activity)

My film The Troubles a Dublin Story, rating score was 7.2 on the 16.7.24 at 3:30pm. When I checked again approx 6:30pm, the film had received a rating of 6, but the title rating had dropped to 6.0. The weighted score remained the same of 7.0 and any which way I try to work out arithmetically, it does not add up, not make sense and I am wondering is this a glitch/error? if so can it be rectified? If not, could I get an explanation as to why this happened? The film is live on SVOD about 14 days and is receiving regular scores from a 1 to 10s, generally in the 5 to 9 range, so no signs of irregular rating activity. I would really appreciate some clarity and resolution on this matter. Best Luke
