I have a similar problem. IGO primo 188.8.131.52654
Swedish postal code looks like this: 143 30 - with a space
when I am search postcode, for a space behind the third digit can no longer enter the remaining two digits, but it is strange that the bottom of the results can be opened.
It might be a silly question but are u putting a space between the post code like this bb7 4nd. im not sure if thats what i was doing wrong but i used another map before i tried putting the space on the old map.
