特定の語がハイライトされない

Question

値域を表現する語の係り受け先の語をハイライトするというプログラムを作成しているのですが
なぜか、値域を表現する語はハイライト出来るのに、係り受け先の語は出来ないという
ことが起こっており困っています。

<dependency_relations.txt>
現在は=>使わず
当日又は=>翌日の
※左辺が値域を表現する語、右辺がそれに係る語

<dict.json>
{強時間:["現在","当日又は"],...}

原因としては、if文の条件が当てはまっておらず抜けているのかなと思っています。
初心者なので助言をいただければ幸いです。よろしくお願いいたします。
