Please check both again, i removed some lines no other meta files seem to have (some lines about reference issues, which were blank).
no need to remove "reference issues" field, it's feature from v1.20.77.2
no issues = blank/empty
if issues = shows missing references and package manager also indicates this package has reference issues (this can be any reference..plugin/texture/hair/)
one example: if you used Ren's Simone hair and not included it with package (to avoid duplicates),
everyone with v1.20+ have Lexi & Simone hair, your package would have reference issues but still work just fine.
Except for v1.19 users (stuck in early 2020)...they aren't worth extra redistribution (same content/dupes).
As for your look/issue well you kinda figure it out already.
First version you had extra root folder, so meta file wasn't working ("file is not valid").
with second/third version meta issue is fixed, but only manual install works.
(since you used same versioning "1.var" package, so client hub doesn't detect update to "version 1").
Try using "New version of existing..." when making package update, so package version is bumped (2.var, 3.var, 4.var...)
Strange that hub allowed you to post an update package with same name and version.
