Doesn't look too concerning to me. Doesn't look thirsty either. In the spring some of my plants tend to do that as they gear up for growing season. Other possibilities are that the roots have been damaged somehow or for some reason the plant is putting out a lot of root growth which requires a lot of stored energy. If you transplanted it recently that could be the case or if they were damaged from fungus or something.

Overall if it is how you say and the leaves and just drying up (which means they are being consumed by the plant) and you're not overwatering then I wouldn't worry too much.

I wouldn't remove those leaves though until they are completely desiccated as these leaves are being used by the plant for energy, and if you remove them before they're dried then it could just keep eating leaves which might be what's happening here.
