These are not ILS that are being displayed, but the DME stations. These of course may also the same frequencies as their coupled ILS. Only Navaids with a defined location position will be displayed on the chart - NDB, DME, VOR, TACAN.
Whether an airport is military or civil is not what is determining whether any on-field Navaid is displayed as a waypoint, but a combination of how close they are to the airport reference point and map scale (and probably the size of your fingertip!).
Zoom out to 750k scale and touch Welshpool. You’ll see the WPL NDB and DME stations listed as waypoints. Touch Norwich and you’ll see the NWI locator.
Zoom in to a really large scale and you’ll see the exact positions of any Navaid, and you can select it as a discrete ‘what’s here’ items to see its frequency.
