Should I be concerned?

Hello community, didn't know about this sub so happy to be here. I'm on holiday with my family and have tested all seven of them. First in a lot of four, which was a clear negative, then a lot of three. I only managed to access the data from this snapshot of the test (cut out before and shortly after). Should I be worried? The test result on the machine itself was negative. Cheers!
