+### Summary
+
+<!-- Summarize the bug encountered concisely. -->
+
+### Steps to reproduce
+
+<!-- Describe how one can reproduce the issue - this is very important. Please use an ordered list. -->
+
+### Example Project
+
+<!-- If possible, please create an example project here on GitLab.com that exhibits the problematic 
+behavior, and link to it here in the bug report. If you are using an older version of GitLab, this 
+will also determine whether the bug is fixed in a more recent version. -->
+
+### What is the current *bug* behavior?
+
+<!-- Describe what actually happens. -->
+
+### What is the expected *correct* behavior?
+
+<!-- Describe what you should see instead. -->
+
+### Relevant logs and/or screenshots
+
+<!-- Paste any relevant logs - please use code blocks (```) to format console output, logs, and code
+ as it's tough to read otherwise. -->
+
+### Output of checks
+
+<!-- If you are reporting a bug on GitLab.com, write: This bug happens on GitLab.com -->
+
