Error coming from formatting.php

I have the Woodmart theme installed on https://www.mintfloors.com.au/ and I am getting the attached error
Warning: ltrim() expects parameter 1 to be string, array given in /home/customer/www/diyfloorboards.com.au/public_html/wp-includes/formatting.php on line 4357

(error.jpg). I’ve found that this error is coming from the Categories.

If I go to the offending Categories (category-screen-causing-error.jpg) I can see that the Category Page Title Image, Categories Navigation and Header Menu have an image attributed to them. I have not done this, and I don’t know where they’re coming from.

I remove them and format it the way it should be (how-it-should.jpg) and all is well.

Then, within a couple of hours, these changes have reverted, and these broken image links reappear and I have to go back into the categories and remove them again.

Attached is also a copy of formatting.php

Please let me know what the heck this is, as the client has just signed the hand-over document and paid me. I don’t want to have this be an ongoing error.
