IQ Testing Discrepancy

I'm hoping to learn from others how you interpreted and applied cognitive abilities scores when there are discrepancies between different tests. Background: My 8 yo daughter began having testing for suspected dyslexia as early as Kindergarten. That was followed by a full neuropsych eval and dyslexia diagnosis at the end of 1st grade. And now she has had gifted testing in 2nd grade. None of the scores align and I'm struggling to understand her true cognitive abilities and what I should be doing to support her. Outside of testing, my subjective observations are that she has high vocabulary and conversational abilities from a very young age. She thinks differently about problems and potential solutions. She has had high emotional intelligence from a young age and understands people and herself better than most adults.

Why are her scores so different from year to year and test to test. I do see she is absolutely drained mentally trying to learn to read with her dyslexia. I am not sure if her effort is changing, her working memory is exhausted, or the test are just looking at different aspects of her cognitive abilities. I don't personally put a ton of weight on her being labeled gifted or average intelligence outside of wanting to understand her and ensure I am meeting her needs. I appreciate any insights from the group!
