been struggling pretty bad with this component, really knocked some confidence out of me 😅😬

When I enter the dates and other inputs and click calculate, it does work (shows the correct amount spent and total investment value). But if I then change the finish date and click calculate again, it shows a very low number (or sometimes 0) for the total value. So it works the first time but not after that.

I think the problem lies in this piece of code which is inside the getTotalVal function:

const purchaseDateObjects = priceData.filter((priceObj) => {

return dates.some(

(date) =>

new Date(date).toISOString().split("T")[0] ===

priceObj.date.toISOString().split("T")[0]

);

});

after changing the finish date, purchaseDateObjects ends up having only a small number of dates in it, missing a lot of them. Or sometimes its just empty, resulting in totalCoinHolding = either an incorrect / low figure or 0.

If I just change the start date there are no problems, just happens with the finish date.

Appreciate any input thanks.
