The Search fields regarding containers seem to have a bug when they can not receive the internal query regarding containers. For example in Specimen Collection if there is no type selected the container Query field stars hovering around waiting for the container data, which can of course not come since there is no type selected.
Im sure you already fixed it somewhere. The same is true for all fields of this kind (i.e.: they need a background promise to fulfilled and idle until they get it). Its not a severe Error just a little nuisance.
and then its fine
