Cell Formula about npoi

[Taha-Di-Nero]

Hi,
Upgrading to Savorboard.NPOI.Core.Ooxml 1.1.4 (was using DotNetCore.NPOI 1.0.0), the problem change to the line when formula are evaluated

WorkbookFactory.CreateFormulaEvaluator(wb).EvaluateAll();
At this line an exception is thrown:

$exception {System.Collections.Generic.KeyNotFoundException: The given key was not present in the dictionary.
at System.ThrowHelper.ThrowKeyNotFoundException()
at System.Collections.Generic.Dictionary`2.get_Item(TKey key)
at Npoi.Core.SS.Formula.WorkbookEvaluator.GetSheetIndex(IEvaluationSheet sheet)
at Npoi.Core.SS.Formula.WorkbookEvaluator.Evaluate(IEvaluationCell srcCell)
at Npoi.Core.XSSF.UserModel.XSSFFormulaEvaluator.EvaluateFormulaCellValue(ICell cell)
at Npoi.Core.XSSF.UserModel.XSSFFormulaEvaluator.EvaluateFormulaCell(ICell cell)
at Npoi.Core.HSSF.UserModel.HSSFFormulaEvaluator.EvaluateAllFormulaCells(IWorkbook wb, IFormulaEvaluator evaluator)

Removing that line everything work fine and somehow when I open the generated xlsx file formula are already evaluated.
Nb: I had ported an export using java apache poi code to .net core and in java was a must eveluting formula before closing WorkBook

Thanks for saving me a lot of time.
