HI Dillon218,
Welcome to the Heartland Owners Forum and to the family. We have a great bunch of folks here with lots of information and all willing to share their knowledge when needed.
The slide is not going to tear or rip the flooring if it is adjusted correctly. There are also rollers that the slide must move on and if one is broken or bolt came out it can cause a problem also.
Maybe you can look under the slide when it is closed and see what is causing the problem and go from there. If you don't get help from your dealer call Heartland, have VIN # and explain your problem in a very nice way. They may have another repair service in your area also that would work on your unit under warranty.
Let us know what happens.
Jim M
