一张截图会有帮助，但仅根据描述猜测，她看到的是 Paratext 8.0 的布局，而我们在 PT9 中不允许删除这些布局。
不幸的是，她必须手动从 _WindowCollections 目录中删除它们（旧文件将带有 .ptwc 扩展名，而不是 .ptwc2 扩展名）。请注意，删除操作是永久性的，因此最好先将它们移到其他地方，确认问题已解决后，再将需要的文件移回。
A screenshot would help, but just guessing based on the description she’s seeing the layouts from Paratext 8.0 which we don’t allow to be deleted via PT9.
Unfortunately, she’ll have to delete them manually from the _WindowCollections directory (old ones will have a .ptwc extension instead of a .ptwc2 extension). Note that deleting them will be permanent, so it might be best to move them somewhere else, make sure that solves the problem, then move any she needs back.
