Your plant is typical of Grammatophyllum growth habits.
They often drop a portion of their flowers. I have never understood why but it happens on about 20% of my plants, especially first blooms.
The yellow leaves match all mine right now. Any drop in temperature will cause this kind of leaf drop. Fortunately this is a fast growing plant. I have had leafless plants in April that were covered with new leaves and flowers in June. (different variety).
The black mushy pseudobulbs frightened me the first time but are the normal growth habit of the plants to discard old bulbs to allow new growth. It can be ignored and will not spread to other parts of the plant. These are very unique growing habits.
Your plant will respond well to a re-potting into a larger container. I find they can double in size each year up to about a 12 inch pot (I like baskets they are more stable).
Whatever you do - do not bury those roots growing straight up. They are a food collection system that traps leaves and organic mattter blowing through the air. They are totally different from the roots that grow down into the pot like other orchids. Grams have two totally distinct types of roots.

Grammatophyllum scriptum martae elegans care instructions
Typical of many grammatophyllum hybridizers the name Tiger Paw is not registered. It appears to be one of many martae or elegans crosses. I have purchased similar under the name Yuan Tiger also not registered.
Yours has exceptionally color coloration. But unless they begin to be cloned (and the market is not big enough for that many orchids) the seed variations will be extensive.
These plants divide very well and can be grown from a single backbulb.
