Based on the search results, I wasn't able to find specific details mentioning New Balance's reasons for the delay in completing the station explicitly. However, there's a relevant article from The Atlantic that discusses New Balance's involvement with the commuter rail station.

In the article "New Balance Bought Its Own Commuter Rail Station", it is mentioned that New Balance opted to fund the construction of the station themselves rather than relying on public funding, indicating their proactive approach to ensure its completion.

For detailed and precise reasons behind any delays, further investigation or direct statements from New Balance or associated developments would be necessary. If additional detailed or official statements are published, they would likely provide the specific reasons behind any completion delays.
