Both errors have the same origin.

Export you pfSense config, and open it with a decent editor, like notepad++.
Locate the 'offending' place : see the error line, its :
installedpackages/acme/certificates/item

First search for installedpackages, your find

<installedpackages>

then, from that point search for <acme>

  <acme>

and now locate <certificates>

Under <certificates> you'll find the <item> sub section.
In there you have a sub section <a_domainlist> and <a_actionlist>
and then you find <name> with the name of what you've defined here :

The issue is : this name in the GUI :

1dc37831-41de-4d05-af38-5703c35ac39a-image.png

doesn't exist anymore in the pfSense certificate manager GUI.

Solution : remove (de install) the acme package.
Then go back to the same place in the config - and save a original version of this file.
If acme stuff is still in there, remove (delete) it.

Import the config back into pfSense.
Install acme again.
