Resolved Manual email settings tooltip: variables displayed, but unused?

OS: CentOS Linux 7.9.2009 (Core)
Product: Plesk Obsidian Version 18.0.33 Update #1, last updated on Feb 26, 2021 08:51 AM

For the email client setup we've been offering the manual client configuration for inbound/outbound host, port & proto in panel.ini. On a testing machine, the configuration in use at the moment reads:
[mail]
clientConfig.incomingServer="imap.testing.local"
clientConfig.outgoingServer="smtp.testing.local"
clientConfig.incomingProtocols="IMAP: SSL/TLS port 993 or STARTTLS port 143. POP3: SSL/TLS port 995 or STARTTLS port 110"
clientConfig.outgoingProtocols="SMTP: SSL/TLS port 465 or STARTTLS port 587"
clientConfig.hideSslNote = true
enableMailboxQuotaWarning = false

At some point in time (not sure exactly after which update, sorry) we've noticed new elements being displayed in the tooltip window:
[manualTitle]
[pop3PortNotEncrypted]
[imapPortNotEncrypted]
[smtpPortNotEncrypted]
How can I edit these? Or get rid of them altogether? Se the attached screenshot. I tried various various entries in panel.ini, in the [mail] section, such as:
clientConfig.pop3PortNotEncrypted="1995"
clientConfig.imapPortNotEncrypted="1993"
clientConfig.smtpPortNotEncrypted="31337"
or:
clientConfig.pop3PortNotEncrypted="UNAVAILABLE"
clientConfig.imapPortNotEncrypted="UNAVAILABLE"
clientConfig.smtpPortNotEncrypted="UNAVAILABLE"
Whatever I try, nothing changes in the UI, still getting the same output as per the screenshot.
Really need to understand what we're doing wrong here. Thanks.

For future reference: mystery solved, we had some custom configuration in /usr/local/psa/admin/application/smb/resources/languages/en-US/controllers/email-address/configuration.php, after renaming the file the tooltip page renders correctly.
