Same fill pattern displaying differently in different projects files.

[mariaZW9XM]

Hi, 

I have a fill pattern for wooden surfaces and it displays differently. I have copied the one on the right into the file on the left and I don't know why the pattern is different (see image). Does anyone know why this happened and how can I fix it? I would like to have it as in the file in the right.

Thanks

Rename the Fill Pattern and try again.
