You seriously need to loosen up this quiz! Remove the Middle Name/Middle Initial from the spelling requirement. Permit nicknames (for instance Pete Conrad or Charles Conrad should be valid spellings for the Apollo 12 Commander. Otherwise, this quiz is impossible unless you've memorized their middle initials!
I think the problem you had is that I made it a fixed box quiz. You have to put the correct answer for the yellow box. You can use tab (or click the desired answer box) to move the yellow box to the desired answer if you need to skip. Don't forget, when the answers appear at the end (or when you type them) they don't necessarily match what will be accepted.
As to type-ins, every astronaut can be found by typing in their full name, with or without initial, their well known nicknames or common shortenings (such as Jim or Tom) or (boring) just their last name. If Apollo XII CDR is highlighted, then "Pete Conrad" does indeed work, and so does Charles Conrad and just Conrad.
I made this quiz because I pride myself on being able to name all the crews for Mercury, Gemini and Apollo. But, the backup crews and capcoms? I'm a space nerd, I'm not crazy!
I tried the first two on your list and they worked for me. The others didn't work because his name begins with a sh- or sch- sound, not an s, and I've never heard of a Schweikart sounding name that ended -ert. So you got me, there are or spellings - that don't sound like his name - that don't work. No idea why the first two on your list didn't work for you, because they do for me. I use Regular Expressions, so that I can be a little more specific than s*h*w*k*rt. I visited this page because I saw someone in some end credits whose name was literally the longest version: SCHWEICKHARDT, which I tested and it also works.

BTW I defy anyone to come up with a spelling for the Apollo 9 LMP's last name that I haven't covered! :-)
schweikart
shweikart
sweikart
sweickart
schweikert

sweikert
There are wildcards you can put in something like s*w*k*rt or something similar which would be helpful. Similar for Apollo 13 command module pilot
schweikart
shweikart
And those did not work for the Apollo 13 CMP.
As to sw not working since his name doesn't begin with that sound, to me that's often slurred and it can be hard to know if it schw or sw
