Magento 2.4.2 Email and Customer Account Name Prefix Problem

[GTLTD]

Hello.

After upgrading our store from 2.4.1 to 2.4.2, I have noticed that customer names are not coming through with name prefixes, but rather numbers? These numbers are appearing on customer orders and in the transactional emails, example 0 Joe Bloggs and 2 Sandra Jeffries?

Anyone else getting this with Magento 2.4.2? This wasn't happening in 2.4.1, nor have customer settings or email templates been changed.

Any help resolving this greatly appreciated!

Anyone able to assist?

Here's some screenshots:

This is an order summary page:

If I try to edit the order address and try to change the number to a name prefix, it does display a proper prefix, in this case Mrs., but if I save it, on the order summary page it still displays a number instead of a prefix. The sales emails also display a number instead of Mr. / Ms. / Mrs.

Is anyone else having this with Magento 2.4.2?

Hi,
we're facing the exact same issue here. 
There is an open issue regarding this problem - apparently something has changed on how guest orders are being saved in sales_order_address.
