My daughter lost one of her school shoes on public transport.
The next morning she grabbed an old shoe and kept her newer one (??) until I pointed out the shoes were slightly different and she would be uncomfortable.
I have seen this metaphorically happen in business. We fix the one thing that is causing us the most pain but sometimes we do not stop to ponder the bigger picture and consequences.
The more it happens without conscious consideration the more a business begins to limp along.
Take some time to stand back to see if you have inadvertently put on mismatching shoes.
