This might happen early in your solution, but it should go away as you iterate. What happens is that FLUENT calculates some value that is below 10 K, which is (probably) unreasonable. To keep the simulation from diverging, it discards the value it calculated and uses 10 K insead.

If the warning does not go away as you iterate, try to find where the offeding cell is. You can do this by going to the adapt by iso-value menu and selecting adapt by temperature. Pick a range of temperatures...

So if you want to use swept, change the "free face mesh type" to "all quad". Then the sweep will turn those quads into all hexa...

Otherwise, perhaps you should be looking into the regular (not swept) blocking.
