Schematic to breadboard layout

You have several problems in your updated version: first on the breadboard the top and bottom 2 horizontal lines are all connected together horizontally (to distribute power and ground usually). The rows above them to the center line for 5 holes connect together vertically the 5 after the center line also connect together vertically (but are separate from the bottom 5) so you have (in a single vertical row) power ground 5 connections bussed together another 5 connections bussed together and power and ground again. The next row horizintal repeats this pattern. The new switches have 2 terminal on each end connected together so as wired on your breadboard the switch isn't doing anything both because it has both terminals connected to a bussed row and because the actual switch is between the two terminals on the left (connected together both internally in the switch and by the breadboard buss) and the two terminals on the right are connected together but don't connect to anything else. If you moved the resistor right 2 positions so that it and the wire connecting it were on the other side of the switch that would work, but you can't physically connect it like that, the switch takes too many positions on the breadboard. To fix this I went back to my original Layout UNO_updated_bb_placed.fzz file which has the complete schematic but nothing on the breadboard (safest place to start), then deleted the current switches in schematic then dragged in and placed the 5 new switches, relabeled and reconnected them. Switched to breadboard and routed one of the switches to show one way they can be connected successfully (they will also work if you leave the switches where they are in your version, connect the resistor between the top 5V bus and move it right two holes then connect a wire from the E column to the F column on the breadboard (across the middle gap) so ground comes in on the left of the switch and the other contact of the switch connects (via the jumper from E to F) to the resistor and the wire to the Uno and the top of the resistor connects to 5V. Then when the switch is closed it will short the bottom of the resistor and the UNO pin to ground as desired. It is possible that if you start from your (or my) original circuit and connect the switches in breadboard correctly it may work, the corruption doesn't always happen (it may be caused by wiring errors like the ones here even if corrected later), but the best way as noted is to start from the schematic only view (or a breadboard only view) as I did for this version:
