Multiclassing into a caster - doesn't show spell dc and spellcasting ability

Hi! I started as a barbarian, then had a couple levels in fighter, and then want to go the rest of the way as a ranger.  (PC sheet D&D5E) However, it: a) doesn't even want to show me I have any spell slot (only managed to fix it by swapping the order in the multiclass setting, as if I FIRST went ranger, THEN fighter; if Ranger is the 2nd class and not the 3d, it does show the spell slots). b) but I can't make it show my Spellcasting ability - Spell DC - Spell Attack modifier on top no matter what( What do I do?

Hi zommie, Please take screenshots of your Core page, Spells page, and Settings page. 

Here they are. Unfortunately, it's not filled in in English :( (the settings are in English, but not the filled in text) I can translate whatever needed. (That's with order of classes already swapped, if I put the classes in the order I've taken them, it shows that I have zero spell slots (if needed, I'll change it back and provide these ones as well)

(I have three saving throw proficiencies because I took the Resilient feat. +2 to Dex and Con saves are temporary buffs during a battle, along with high AC, etc. None of them are the reason it happens, it was like that before them.)

Zommie,  If you click "None" on the spellcasting page (above "Spellcasting Ability") you can change it to the relevant ability. 

oh, I had tried it initially and it didn't work, no response, it wasn't active. I thought it wasn't possible. Tried now in another browser, and it worked! Thank you! (still strange though that if it's the 3d, and not the 2nd class, I have no spell slots shown)
