Wrong cdr v5 and v6

Friends, I createdASTPPCOM-890in jira and you made the correction at the time.
But I migrated to version 6 and the error came back, don’t you merge the master version in github?
Will you have to make the correction again?
Can I use the same fix from v5 in v6? I already created ASTPPCOM 120 for v6 but no answers…
