I cant build a crafting table

Alright so I'm not to sure what's going on but it's been happening for 2 days now, when I'm in a sever like for example i was on mineplex and then I hopped onto survival, got the wood and tried making a crafting table I have enough plants for it and it shows that but then after i click on it it pops up in my hot bar for a slot second then the wood returns to me and i cant build. I dont understand also certain blocks dont work for me like nether brick.
