If there is any doubt, there is no doubt!
I wouldn't simply say that, because one might be simply ignorant
The point I was hoping to make is that one needs to establish the full extent of the problem, before saying it doesn't matter.
Another example might be a non-working instrument panel lamp. You change the bulb but it still doesn't work. Most people would not worry about it. Only a bulb... But what if the cause is a damaged wire harness, rubbing against a metal bulkhead, with a much more vital wire about to short to the airframe, and .... there is a fuel leak nearby?
discuss it with your instructor
Sadly, IME, instructors often do ignore problems like this.
