Duck be a Lady clear scores different

In sub 2 of Webbed Wonder, the top scores in my bracket (3.8) are showing different scores after the initial clears. There are a few with 18878, which is the usual score as far as I recall, a few with 18877, a few with 18876, and a few on 18875. There may be a bigger range, but I can't see any further down.

I wonder if it’s a bug with scl8, my score in 1.9 is 19146 and the leader board around me are all the same.

I am seeing the same thing in my bracket, 4.8. The next score below 18875 is a long way back, so I think those four scores represent the full spread.
