Multiclassing a Druid and Sorcerer spell slot bug

I had a player of mine make a lvl 1 Sorc. and lvl 4 druid. I noticed on the character sheet that level 3 spells were available. Correct me if I am wrong but this is only available to level 5 druids. This is what I see in the "spells" section of the character in dndbeyond:

• 1st lvl spell slots - 4 available
• 2nd lvl spell slots - 3 available
• 3rd lvl spell slots - 2 available

In the 3rd slot, I do see spells have the "level 1" casting to them so I am assuming these are 2 spell slots given by the Sorcerer class but only labeled at level 3. I recreated the problem twice and confirmed it is a bug. I believe my player had at least 1 level 3 spell selected but now I cannot confirm that and it will not allow level 3 spells to be chosen. Is this a bug or is this desired to separate the spell slots of the druid from that of the sorcerer?

I get it. So this is as intended. I thank you for your information and just question the reality the programmers of the system live in. :)

Personally, I think it is slightly misleading and I would wonder why they would not label it as Druid 1st level spell slots or Wizard 3rd level spell slots instead of arbitrarily counting upward. As a DM, I try to talk my players out of multiclassing to avoid some of these confusions but I will never take away their ability to choose.
