item description image overstretched in category / items list view

We've added tiny calendar icon to the description of some items.

As it can be seen below

the little calendar icon renders as expected.

On the items list view, however, the same image appears in the wrong place and totally overstretched.


I've noticed that the image address in the item list view includes very high width and height values via URL parameters:

com_flexicontent/librairies/phpthumb/phpThumb.php?src=/images/stories/icons/calendar-icon.png&w=200&h=200&aoe=1&q=95&f=png


Is this a bug or are we missing some display option?

Thank you in advance.

Environment:
Joomla 3.7.3
FC 3.1.1
PHP 5.6.7

Hello

are you using category layout of our "blog" template ?
it has configuration parameters for the image size

Hi. Thanks for the prompt reply.

We're using a custom category layout.
Can't any display config options anywhere on the layout admin interface.

Hello

this custom layout is a copy of which layout ?
e.g. is it a copy of 'blog' layout and the you edited category.xml file to remove the parameters ?
