Laelia tenebrosa II problem

The brownish patch on the pseudobulb of my newly purchased Laelia tenebrosa II appeared to be spreading. At least I noticed some slight increase of its area.
Of course I freaked out and cut off the whole pseudobulb sprinkling some cinnamon powder on the cut:



Now there is still some dark spot on the lower part of older pseudobulb (behind the cut on the picture above) and darkish spots on the protective sheath of the newest pseudobulb:



With my limited experience with cattleyas I am very close to throwing away the whole plant.

Is there any reason I shouldn't?

Laelia tenebrosa II problem

This purplish-brownish patch on the pseudobulb of my new laelia tenebrosa. I was thinking it is a sunburn:



When I received the plant, I put it on my south-east window with other catts and this pseudobulb was looking directly on the sun. Well, I never saw sunburns on my cattleyas, but it does look like a patch on one of my vanda seedlings that got burned by sun for sure. On the other hand, as far as my knowledge extends - it might be some nasty rot.
So, at this point I am not sure if I should leave it alone or is it better to cut off the pseudobulb in question or even throw away the whole plant(I would like to avoid this option though).

Any suggestions, please?

On a happy note - there are multiple roots starts on the newest pseudobulb that is healthy for now:

Laelia tenebrosa II

Laelia tenebrosa is the last one from the cattleya batch that I got from Clouds. I know, it can grow pretty large and I already have small tiny seedlings of this species, but it was pretty hard to pass an opportunity to get larger sized plant(it was listed as large seedling) that might flower sooner so I would be able to enjoy blooms in this life.
Since I usually try to buy mostly smallish species, I think I will be able to squeeze this large laelia in between vandas on my sunny window.



There are four pseudobulbs, bunch of nice roots, leaves are freshly green. I moved plant from plastic pot with bark mix to my preferred clay pot with chc.
