`tcolorbox` への参照が機能しません

`tcolorbox` への参照が機能しません

私は自分のテキストで例の 1 つを参照しようとしているのですが、常に上の前のカウンター (ここではセクション番号) でラベル付けされています。

exmp私の例の環境は、環境そのものとして定義されていますtcolorbox。問題はおそらく私のnewtcolorbox定義から生じていることはわかっていますが、どこから来ているのかわかりません。何か心当たりがあれば教えてください。

私はpdfLaTexコンパイラを使って作業しており、ここに最小限のコードがあります:

結果はこうです

それが何を与えるか

どうもありがとう。

解決済み:

問題は確かにパラメータ宣言にあり、必要なパラメータは 1 つではなく 2 つでした。#1 がオプションで、#2 がタイトルになります。解決策のコードは次のとおりです。
