Line Charts not rendering after saving workbook to file

[SamueleSV]

Hi, I'm using Spire.XLS 14.3.3 nugets in a C# WPF project, I made a big update recently, going from Spire.XLS v11.4 to Spire.XLS v14.3.3 and in my workbook I have pages containing line charts that takes series values from some hidden pages in the same file, after the update it seems like the charts don't get rendered in PDF nor in Excel (the chart object gets correctly inserted in the document but no data is loaded inside), it says that the data source for the chart is too complex to visualize, but the data source is just 2 series (one per row)
