Norgate-s-OriginalCloseTimeSeries-indicator-exception-upon-conversion-of-Blocks-to-code

I got the following error when using the OriginalCloseTimeSeries indicator. I did some tests seems it happens when it's on Weekly timeframe with C# code strategy. I attached screenshot for a sample block based weekly strategy on SP900. With the block version it works fine, but when it's opened as a C# strategy, I got the error.

CODE:
Initialize Exception (LO-201506) Line 22 - Index was out of range. Must be non-negative and less than the size of the collection. (Parameter 'index')
Initialize Exception (LTM-201506) Line 22 - Index was out of range. Must be non-negative and less than the size of the collection. (Parameter 'index')
