I installed the latest version (3.2.2) of https://wordpress.org/plugins/duplicate-post/ to my WordPress. While running plugin checksum with cli version 1.5.1 I get the following error:

| duplicate-post | duplicate-post-jetpack.php | File is missing |
| duplicate-post | duplicate-post-wpml.php | File is missing |

Those files are indeed missing, but they are not in the original plugin zip either. It seems that they've been moved into compat/ folder a few releases ago.

It seems that https://downloads.wordpress.org/plugin-checksums/duplicate-post/3.2.2.json still returns those two moved files and their checksums in the root of the plugin. Could there be some issue in the cheksum endpoint so that it keeps deleted files in it even though they do not exist anymore?

Edit:
Also it seems that https://downloads.wordpress.org/plugin-checksums/duplicate-post/3.2.json does not return those two missing files and their checksums at all.
