Querying for non-zero values does not seem to work

Hello--

The following query searches for all competitor in Mexico with a yield that is greater than zero. However, result does list competitors with zero yield. {{#ask:[[CompetitorlName::<q>[[Country::Mexico]]</q>]][[Yield::>0]] |?Date |?Yield |format=table }}

However, this query eliminates those competitors with zero yield {{#ask:[[CompetitorName::<q>[[Country::Mexico]]</q>]][[Yield::>0.000001]] |?Date |?Yield |format=table }}

Am I doing the first query incorrectly somehow?

Use {{#ask:[[CompetitorlName::<q>[[Country::Mexico]]</q>]][[Yield::≥0]] |?Date |?Yield |format=table }}. Alternatively, set $smwStrictComparators to false.
