Under some circumstances, modifiers are evaluated more than once. One time to compute the actual output geometry and another time with `MOD_APPLY_ORCO`. This design probably has to be revisited at some point in the context of geometry nodes. However, that would be much more involved than a bug fix. The issue was that during the second evaluation, the node tree is evaluated based on a slightly different input geometry. The data generated during the second evaluation overwrote the cached data from the first evaluation, resulting in incorrect data that is shown in the spreadsheet. The fix for now is to simply not log any data in the second evaluation.
