Simple Prompts not understood , even in non-fast mode

Hi, 

I was just having look around and did some testing and started with very simple prompts, I tried a very ordinary prompt to say design a pic that has some simple words written like example "abc" or "xyz", (always a single word) the output pics that will get generated will have text that would be truncated like say only one or 2 alphabets in the picture.
Is there something wrong I am doing with prompt ? or is this a model limitation. 

thanks.
