*Solved* Using Tilemap introduces white line into textures

Hi there

I have just started using Construct 2 and have come across an unusual problem that I can't seem to sort out.

Whenever I add a tilemap image into my level, wherever the 2 overall maps meet, a white line appears out of nowhere. Which is not present on the actual texture/tilemap itself.

Here is an image to show what is happening, if anyone knows how I can get rid of this I would be very grateful.Thanks

Well infact I am apparently not allowed to post any images so this will be much trickier to explain the issue fully, unless this is a commonplace occurence that people know of? Thanks

Ok sorry nevermind, when I test play the lines disappear so they seem to merely be in the editor to indicate seperate tilemaps. Thanks anyway.
