Project Languages statistics

Hi everyone, I have this project https://github.com/arielcarrera/environment-var-replacer and I see in languages statistics 60.5% Dockerfile…

Are statistics calculated right ?

Project files:
XML : 19
Batch: 4
Dockerfiles: 2
Java: 2
Shell: 2
Markdown: 1
Maven POM: 1
Text: 1
Yaml: 1
Ignore List: 1

This is a Java Maven Project and I have only 2 dockerfiles so… why Dockerfiles is 60% and Java isn’t in the statistics ?
