oncidium with browning pseudobulbs?

[jayayay]

Hi, I recently bought an oncidium from Lowes a few weeks ago. It looked completely okay when I first got it. I then repotted it a few days later with an orchid bark mix which caused some of the leaves to yellow a bit. I'm pretty sure that's normal after a repotting though, and I only really had one leaf completely fall off.

Now though, about two weeks later I have some of the pseudobulbs turning a brownish color. (this has also happened with all my previous orchids). The bulbs feel slightly softer than the other okay ones. I did just water the orchid on Friday and the previous time was back when I first repotted it. Am I just overwatering it?

I did repot the orchid again today after cutting off the brown bulbs and dead roots. the cut edges also got some cinnamon put on them.
