Well, if it doesn't, there are several hundred million incorrectly designed coins out there!
And they're normally called Bicentennial dollars, not liberty bell dollars.
Bottom line, it's quite intentional. The design was intended to honor both the country's 200th Anniversary (hence the Liberty Bell) and its scientific progress (hence the moon, because the space program was very active in the 1970s)
Coin designs go through lots of planning and "vetting" before release so it's definitely not a mistake.
Only the dual-dated (1776-1976) ones issued to mark the Bicentennial have those images. All other dates carry a design honoring the Apollo 11 moon landing.
It's BIG (38.1mm) and has a bust of Eisenhower on the front & the Liberty Bell and moon on the back.
The front looks the same as any other Eisenhower dollar, but with 1776-1976 for the date. Then on the back, it shows the Liberty Bell and the moon.

On the reverse of the bicentennial silver dollar is the Liberty Bell super-imposed over and image of the moon.
That's the bicentennial dollar, extremely common, and still worth one dollar.
Bicentennial, not centennial. 1776-1976 is two hundred years. Bicentennial commemoratives have the Liberty Bell and moon in their design. Other dates have an image of the eagle landing on the moon. In circulated condition these coins are interesting curiosities but have no extra value. Uncirculated copper-nickel ones are worth about $2. Uncirculated 40% silver Bicentennial dollars are in the $7-8 range.
The moon is on the back of all 1970s Eisenhower dollars. It was in recognition of the moon landing.
??? Roosevelt is on the dime, not the dollar. If you have a large coin (about 38 mm in diameter) with a picture of an eagle landing on the moon on its back side, you have an EISENHOWER dollar. Assuming it's from circulation, it's made of copper-nickel, not silver, and is only worth face value.
The phrase "E Pluribus Unum" is Latin for "one from many." This is the national motto of the USA, and has been on every coin minted by the US Mint since its inception in the late 1700's. The half-dollar with the profile of Benjamin Franklin on the obverse does indeed have the Liberty Bell and an engraving of the moon on its reverse.
The reverse of the SBA dollar is more-or-less a smaller-scale version of the image on the back of the Eisenhower dollar: an eagle landing on the Moon.
