In the "To" column of the message list, To-fields containing at least one address formatted as <...@...> and a comma are displayed only as the comma (so the "interesting" content, the email address, is not shown.
To fields like
are shown correctly in the message list.
To fields like
To: "Alice" <firstname.lastname@example.org>,"Bob" <email@example.com>
break (only the comma is shown).
That's not the case here. Your "broken" examples are all shown correctly.
Need more info. Is this the case for every message or just some?

I hope the picture clarifies the problem. I have been using claws-mail for ages and never noticed this problem before. I still don't have many message where the problem occurs. But, sending a message to <firstname.lastname@example.org>,<email@example.com> is sufficient.
What option do you have selected for 'Displayed in From column' (yes, From column) on /Configuration/Preferences/Display/Summaries, Message List frame?
And do uou build Claws Mail yourself from the official tarballs, or use a distro package? If the latter, which distro?
Regarding the last question, I see you use FreeBSD. Is that self-built?

Screenshot of message list preferences
I attach a screenshot of my message list preferences.
The “Display sender...” preference has no effect on the comma. I can tick it on or off (it does have the intended effect on the display of the sender's name, though).
I use FreeBSD dell 12.1-RELEASE-p1.
Claws-Mail is installed from packages with the following Options
COMPFACE : on
DEBUG : off
DOCS : on
ENCHANT : on
IPV6 : on
LDAP : off
NLS : on
STARTUP : on
THEMES : on
Meanwhile I have replicated the problem also on Debian Buster with kernel 4.19.0-6-amd and Claws Mail 3.17.3
Are you able to build and test the current GIT code?
I would really like to compile claws-mail from git but this seems to be harder than I thought.
On FreeBSD claws-mail should compile at least from packages, but it doesn't (fails with two different machines, I have informed the package maintainer). Apparently neither GTK nor X are found.
I have then tried to install on Debian Buster. There configure.ac starts with “possibly undefined macro: AC_LIB_PREFIX” until configure stops with “cannot find install-sh, install.sh, or shtool in config "."/config”.
I short: I fear, I am just not capable to install claws-mail from git :-(
One afterthought: The broken “To:” field is rendered correctly in Sylpheed 3.7.0.

Claws Mail has diverged so much over the years to make that irrelevent. But, anyway, as I said, it works fine here.
Re-open after the next release if you still have the issue.

Building Claws Mail from git is trivial on Debian:
