Error thrown in powershell when `show-stats` is used while application is empty

[IronBiscuit]

The image above shows the result I see upon entering the clear command. While everything is working as intended so far, upon entering the show-stats command, an error is thrown on my powershell, as shown below:

Team's Response

Thank you for the bug reported

Accepted because this is a flaw, however, the severity should be low

From the guideline: severity.Low : A flaw that is unlikely to affect normal operations of the product. Appears only in very rare situations and causes a minor inconvenience only.

For this flaw, it does not affect the normal usage as the application does not crash and there will still be a table showing the statistic, which is empty in this case. This can tell the users that there is actually no expenses yet. Thus, it does not affect normal operations of the product

It appears in very rare situation because the when users see there is no expenses in the expense list, he is very unlikely to use show-stats. Thus, this situation does not likely to occur very often.

Thus, in conclusion, it is some flaw that we can improve more, but we think that the severity should be low.
