The Sun Blade mentions proficiency twice in its description on D&D Beyond.

The first one is about being proficient with shortswords or longswords:

If you are proficient with shortswords or longswords, you are proficient with the sun blade.

The second one is about proficiency with a longsword and only longsword:

Proficiency with a longsword allows you to add your proficiency bonus to the attack roll for any attack you make with it.

The latter phrase is absent in the printed version. Is it just redundant? Where did it came from?

Ignore the last statement about longsword proficiency

This is a bit of a guess, but I'm pretty sure that last additional statement about longsword proficiency is a side-effect of how D&D Beyond works. When you create a magic weapon or armor, you have to specify a weapon or armor type that your item is based on.

An additional sentence is then added automatically to the description stating basic proficiency rules or appearance.

This is actually a problem for items that specifically state special properties in the description that overrule general proficiency rules or appearance - the Sun Blade being one such example, where proficiency in either longswords or shortswords allows you to be proficient in using it. (And I've hit the problem myself when creating homebrew items!)

The same item in the Dungeon Master's Guide book (page 205-206) does not have this additional sentence, lending evidence that this last sentence is just a "D&D Beyond implementation issue".

@Someone_Evil provided this link to the Sun Blade in the DMG compendium for comparison. It does not include the second portion you quoted; that is copied directly from the entry for the regular longsword.

    \$\begingroup\$ PJRZ, your guess is correct. On DDB, the standalone descriptions of all magic items that are weapons (e.g. longsword, +1) include the generic description of the mundane weapon (e.g. longsword) at the end of the description. The same is true of shields (e.g. shield, +1) and armor (e.g. scale mail, +1). \$\endgroup\$

    \$\begingroup\$ @V2Blast: I hit this issue when I created a home-brew "Roach Armor" - armor made out of chitin with its own unique appearance with the same base AC as breastplate. Except you can't just pick the armor stats - I had to base it off "breastplate", which then added an irrelevant description at the end of my own. I had to add note to my description to say "Ignore description below!" \$\endgroup\$
