This is a big mistake. Always modify your existing job descriptions to reflect the requirements of the grant announcement. Another mistake is to submit stained and faded job descriptions and other supporting documents that are barely readable. All documents in a grant application need to be easy to read, clear, and fresh. Not only do you loose points for this, but you also loose the respect of the reviewer for your application.
Reviewers can smell a rat three thousand miles away.
Items such as rent, renovation, information system development, and consultants always raise the ire of most reviewers. If you have these categories, make sure they are discussed in the narrative somewhere and make sure the cost is reasonable. Write as if the money is coming out of your bank account. This is where many grants loose points. Accountability is a real and major issue with governments and foundations.
