PS 1.7.6 package .git repository conflicts

[grsinternet]

Hello,
we are uploading each project to Git, but all the time we have issues with some vendors:

Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git checkout -- <file>..." to discard changes in working directory)
  (commit or discard the untracked or modified content in submodules)

    modified:   modules/psaddonsconnect/vendor/guzzlehttp/cache-subscriber (modified content)
    modified:   modules/psaddonsconnect/vendor/guzzlehttp/ringphp (modified content)
    modified:   modules/psaddonsconnect/vendor/guzzlehttp/streams (modified content)
    modified:   modules/psaddonsconnect/vendor/prestashop/circuit-breaker (modified content)
    modified:   modules/psaddonsconnect/vendor/react/promise (modified content)

no changes added to commit (use "git add" and/or "git commit -a")

 

Does anyone have similar problem?  Maybe it would be a good idea to remove .git from these repositories
P.S. this is not starting error I get, but this vendor always conflicts in development...
