Unable to execute SQL query command

Hi All,

Below is the current customer deployment, We encounter issues with missing data control information for certain date 11th until 16th December 2020.
We have logged a case with Support and provided with SQL query to extract information. However, we encounter weird query report whereby instead of 2019 the error was trying to convert nvarchar value 2014.

Anyone encounter same issue or can help solve the solution?. Thanks

Sophos Environment:-

SQL Query & Error:-

SELECT * FROM [SOPHOS550].[Sophos Reporting Interface].[vEventsDataControlData] where EventTime >=2019-12-12
