Bundesliga 2015/16 match file appears to contain only 34 matches instead of full season

Hi StatsBomb team,

I noticed a possible issue with the open-data match metadata for the 2015/16 Bundesliga season.

The 2015/16 Big 5 release identifies Bundesliga as:

• competition_id = 9
• season_id = 27

However, when loading the current master version of:

data/matches/9/27.json

I only get 34 matches.

For context, the other 2015/16 Big 5 leagues return the expected match counts:

Premier League   380
La Liga          380
Serie A          380
Ligue 1          377
Bundesliga        34
Total           1551

I would have expected Bundesliga 2015/16 to contain 306 matches, giving a Big 5 total of 1,823 matches with available match metadata.

Minimal reproduction:

import requests
import pandas as pd

BASE_URL = "https://raw.githubusercontent.com/statsbomb/open-data/master/data"

def get_match_data(competition_id, season_id):
    response = requests.get(
        f"{BASE_URL}/matches/{competition_id}/{season_id}.json"
    )
    response.raise_for_status()
    return pd.DataFrame(response.json())

bundesliga_1516 = get_match_data(9, 27)
print(len(bundesliga_1516))

Current output:

34

Expected output:

306

This may be related to a recent update to the open-data repository. I am using the data for academic work, so I wanted to flag it in case the full Bundesliga 2015/16 match file was accidentally overwritten or reduced.

Thanks for maintaining this dataset, it is extremely useful for research and football analytics.
