Default component names have an integer suffix, eg textInput42.
If the component is copied (eg by Copy/Paste) then of course a new name is required. Retool does this by updating the suffix, eg textInput43.
But if the component is simply moved by Cut/Paste there is no need to rename it by updating the suffix.
But Retool currently does update the integer suffix on Cut/Paste thus creating a new name.
This means that any references to the component will no longer work and would have to be updated by hand. In some case this can be very tedious and introduce the risk of errors.
Please do not update component names when they are moved by Cut/Paste
