"allowed units violation" where no units are required

[ubahnverleih]

I found some strange behavior: On some properties like P1301, which don't require any units i get a "Constraint violation: allowed units violation". I selected no unit.

Maybe you can reproduce with this example. On Suzhou IFS i get Constraint violation: allowed units violation - with value 62.

Just realilized, that the unit=Q11573 was put into the Permalink URL. If i remove that, it works. But it looks like, that in some cases units are cached and not removed if no value is selected as unit.

For some reason it tries to use meters as unit.

I had another case, where it tries to use meters instead of kilometers per hour.
