FNCSpreadGrid copy/paste issue

There's an issue with copying & pasting formulas in FNCSpreadGrid.
How to reproduce:
1-Open and run VCLSpreadGridDemo from FNCSpreadGrid Demo folder
2-on C3, I put the formula "=a3+b3", then CTRL+C
3-on C4, paste (CTRL+V), ok, the formula will be "=a4+b4"
4-on C5, paste again (CTRL+V), the formula will be "=a3+b3", and this will be the formula on every subsequent paste, unless I copy it again.

Only the first paste is making the right cell reference conversion.

Thanks for reporting.
We could locate this issue and we'll fix this for the next update.
