Very strange issue with MATCH function.

EDIT: I realized my mistake, I didn't specify "Exact match" in the 'MATCH' formula. Problem solved. Original post below.

Hi.

I've found something I've never noticed before, which is that the MATCH function can easily be thrown off by the presence of text in certain cells.
In my example file, attached, you can see this clearly in Example 2 to 4.
In example 5, I changed the word "List" to "1.List", which seems to work.

I have many INDEX-MATCH formulas in my own report that are thrown off by the presence of these words (I absolutely need those words) & I have no idea why this error is happening, it makes no sense.

Does anyone understand the error & know a workaround or is this a bug?

I've attached my example file & a screenshot as well just in case.
