There have been one or two new versions of SuiteCRM 7.7 since your post.

Would it be possible to upgrade to the most recent version and try again?

If you’re able to replicate the issue again on the most recent version, you may wish to take a look on our github repo to see if someone has raised it:

If not, please feel free to raise this as an issue, and a developer will investigate!
