Powerpoint graphs not updating

I have 30 charts that were created from excel and were pasted onto powerpoint slides.

Every month, I have to update these 30 embedded charts by manually clicking on the charts and edit.

The calculations are set on automatic for the workbook. I tried setting up an other chart in the same worksheet, linked to only one simple row and this new chart has the same refreshing issue so I suspect it has to do with settings or something like that but for the life of me I can't find which settings could do this.

Every time I want to see an updated version of it I have to either delete the serie and add it again or re-open the file.

In simpler terms, a bank with excess cash, which is often referred to as liquidity, will lend to another bank that needs to quickly raise liquidity.

If the location of either the Power Point presentation or the Excel file changes, you may have to embed the chart again in order for it to display correctly.Paste special option does not allow users to edit the charts. However, I am getting a pop up menu asking to update the file in my documents folder. Would you like to answer one of these unanswered questions instead?Hence, I am unable to use this paste special option. My source i.e excel file is located in my desktop folder. Use the assigned data series variables (a, b, c, etc.) together with operators ( , -, *, /, ^, etc.), parentheses , and constants (1, 1.5, 2, etc.) to create your own formula (e.g., 1/a, a-b, (a b)/2, (a/(a b c))*100).As noted above, you may add other data series to this line before entering a formula.
