Dictionary Look Up Problem (when dictionaries for more than one language are selected)

A problem after the system upgrade to High Sierra —still not addressed in 10.13.2 (I wonder if that is a problem particular to my system):

If I have dictionaries enabled for more than one language (say, the New Oxford American plus any non-English dictionary are selected under Dictionary> Preferences) "quick look up" of a word common to two or more of the selected languages will return results for only one non-English language.

For example: 1. if Oxford-Hachette dictionary is checked under the dictionary preferences: Quick look up of the word 'solution' will only list the French-English definition, not the entry in the New Oxford American Dictionary (even if the latter was given priority in the dictionary preferences).

2. if Oxford-German dictionary is checked: Quick look up of the word 'spiel' will only list the German-English definition, not the entry in the New Oxford American Dictionary (nor the entry in the Oxford-Hachette for that matter. Yet it will display the definition in the Duden-Wissensnetz dictionary, a German to German one.)

I hope this will be fixed soon.
