[Bug]: new Shallow diffusion bug?

### 系统平台版本号 win7 ### GPU 型号 3060 ### Python版本 3.8.9 ### PyTorch版本 1.13.1 ### sovits分支 4.0(默认) ### 数据集来源（用于判断数据集质量） UVR ### 出现问题的环节或执行的命令 train Shallow diffusion ### 情况描述 May i know that is it same content between train.txt and val.txt ? the below files train.txt & val.txt are auto gen by Sovits, why i have 10 wav but only 2 wav show in val.txt? is it mean Sovits will only train ./dataset/44k/Ai_mary/ocalsV2_8.wav and ./dataset/44k/Ai_mary/ocalsV2_10.wav ? thanks ! train.txt ./dataset/44k/Ai_mary/ocalsV2_1.wav ./dataset/44k/Ai_mary/ocalsV2_2.wav ./dataset/44k/Ai_mary/ocalsV2_3.wav ./dataset/44k/Ai_mary/ocalsV2_4.wav ./dataset/44k/Ai_mary/ocalsV2_5.wav ./dataset/44k/Ai_mary/ocalsV2_6.wav ./dataset/44k/Ai_mary/ocalsV2_7.wav ./dataset/44k/Ai_mary/ocalsV2_8.wav ./dataset/44k/Ai_mary/ocalsV2_9.wav ./dataset/44k/Ai_mary/ocalsV2_10.wav val.txt ./dataset/44k/Ai_mary/ocalsV2_8.wav ./dataset/44k/Ai_mary/ocalsV2_10.wav ### 日志 ```python - ``` ### 补充说明 _No response_
