That's not a category ID, i thing the code location and if you're using the Delta theme, look for the
item.php file. You can try
starting on line 199, look for the <!-- HEADER & BASIC DATA -->
for desktop/ tablet, location section.
in line 207,
<div class="location">
<?php if($location <> '') { ?>
<a target="_blank" href="
https://maps.google.com/maps?daddr=<?php echo urlencode($location); ?>">
<?php echo $location; ?>
</a>
replace with ==>
<div class="location">
<?php if($location <> '') {
//
Remove the comma and number or up to 3 capital letters at the end, example: ", JAK"
$clean_location = preg_replace('/,\s?([A-Z]{1,3}|\d{1,3})$/', '', $location);
?>
<a target="_blank" href="
https://maps.google.com/maps?daddr=<?php echo urlencode($clean_location); ?>">
<?php echo $clean_location; ?>
</a>
and starting
line 307, <!-- HEADER & BASIC DATA -->
for mobile, location section, you do the same thing
