Rick is correct about the fault, unless you poured something with a lot of solvent into the carpet in those areas. Is the building owner looking to you to repair at your expense? If not, leave it to an installer with commercial installation experience to fix. If they are aiming at you, hire an inspector with commercial installation experience to keep from having to pay for the correct installation.
I've seen a bunch of poorly installed direct-glue installations that came up with cleaning, and learned that the installers knew they were hacking the jobs when they did the installs. They told the building owner that the carpet could only be dry-powder cleaned. Inspections showed they used a worn trowel in most areas and in the worst areas there was no adhesive at all.
