Having problems With text amounts over 71 can anyone help?

Hello, Sorry in advance because this question will take a lot of explaining to ask. Also, I am relatively new to unity so I am sorry if this is something people should normally know. I have a game I have been working on it has 24 inventory slots per inventory page and there are 3 pages. I have got the icons working where if the number for whatever slot equals the item id then the texture will show. I made an info page with the descriptions and names for whatever item is in the current slot the player has selected. I have 320 items total with all of the names textures and descriptions for all of those items filled in. If I change the item id and it is lower than 71 then the name description and texture all change correctly, but as soon as I reach item id 71 the text values freeze at what they were last at till I make it lower than 71 again but the textures change like they should for every one of the 320 items including item 0 (a blank item) what am I doing wrong and why will the texts not change above 71 is my question.
