Clear blue question

This morning I decided to test with clearblue for the first time. It was Clearblue Rapid detection. I wish I would’ve taken a picture of what happened but initially when I peed on it, it looked like there was dye run. But then after 3 minutes the dye run was gone. The test window had a line in it that didn’t look like a complete line. It was more like 3/4 of a line. I’m just wondering if this test was invalid? Has anyone noticed weird dye running with the clear blues that disappears before the test is complete?
