The file labeled as `readme.md` seems to contain CSV formatted data rather than Markdown content usually expected in a README file. This indicates a mislabel or misuse of the README file which is supposed to contain descriptions of the dataset such as its purpose, structure, and how to use it, not the raw data itself.

Issue 1:
- **issue**: "Misused README file"
- **evidence**: "'machineID','model','age'\n1,'model3',18\n2,'model4',7\n..."
- **description**: "The 'readme.md' file contains CSV formatted data, which is unusual and not according to standard practices for README files. READMEs are expected to offer descriptions of the datasets (purpose, structure, usage instructions) rather than contain actual data. This misuse leads to unclear dataset description and preamble necessary for understanding and utilizing the dataset effectively."

Given the unexpected content in "readme.md," I will now check the content of the second file, presumed to be the actual data file, to understand if there are further issues, especially around missing dataset description or information.The second file actually contains the description that one would expect in a README or similar documentation file. It describes the dataset, its context, components, and provides specific details about the types of data it includes, such as telemetry time series data and errors encountered by the machines.

Issue 2:
- **issue**: "Dataset description located in an unexpected file"
- **evidence**: "# Microsoft Azure Predictive Maintenance\n\n## About Dataset\n\n### Context\n\nThis an example data source which can be used for Predictive Maintenance Model Building..."
- **description**: "The content expected in a README file, which should describe the dataset, its structure, usage, and details about its contents, is actually located in a file that was presumed to be a data file. This misplacement leads to unclear dataset description and potential confusion for users trying to understand or use the dataset. It’s important for such descriptive content to be correctly placed in a designated README file for easy accessibility and standard conventions."

These issues present a clear deviation from the standard expectations outlined in the hint - namely, unclear dataset descriptions and missing information due to the improper use of files and misplaced dataset documentation.
