[tooltip] "Dockerfile seems to be invalid" although it is in fact valid

[NgxDev]

For any of the Dockerfile files in my project, even for the simplest one, such as:

FROM nginx:latest

if I go into the SCHEME view and hover over the small Info icon next to the word Dockerfile, a tooltip appears saying: Dockerfile seems to be invalid

DockerStation version: 1.3.0
Docker for Windows: 17.09.0-ce, build afdb6d4
OS: Windows 10 PRO (1709)

So. I don't understand the issue :)
What is problem?

My point is that I think the tooltip is wrong. I'm no docker expert, but I think that the Dockerfile is actually valid.

Other than that, thanks for a wonderful product! I love it!
