Warning when using "official" slsqp data

When processing bbob/2020/SLSQP-11-scipy, I get the following warnings

and many more with "less than 15 instances in the set" [4, 75, 2, 73, 79] (f6, 2D), [1, 72, 78, 5, 76] (f21, 2D), [4, 75, 2, 73, 79, 1, 72, 78, 3, 74, 80, 71, 77] (f8, 10D), [1, 72, 78, 5, 76, 4, 75, 71, 77, 3, 74, 80]...

The read data themselves look fine, all functions have the 15 instances [1, 2, 3, 4, 5, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80]. The distribution of the data over several files or folders seems to trigger the (unnecessary) warnings which is probably somewhat new?

Will be fixed with the next push.
