Release tab issue related to double installation

We have installed and used sentry in several projects now, and some projects include other projects as libraries.
However, in this case, in the Release tab of the sentry dashboard, the updated version of the sentry project library included in the parent project is posted together with the release details of the parent project.
That is, the release version of the parent A project is mixed with the release version of the child B project.
It seems that this has not happened before, but what part should we look into?

Which version of Sentry is this?

It is 20.11.0 version.

That’s quite an old version so as a first measure, I’ll ask you to try upgrading to a more recent version like 21.7.0.
