Microsatellite shifts (peak calling) GeneMapper! Thesis help!
Your markers are probably fine, especially because you keep seeing the same allele in multiple individuals. Dinucleotide repeats do not always copy perfectly. More likely, remember that the primers you use to amplify your microsatellites bind outside of the actual repeat region. You could have an insertion/deletion in the region between the primers and the repeat region, changing your allele sizes from to even to odd (or vice versa).
