I'm neither a Briton nor an English language wizard, but I considerably believe I can offer sort of assistance here. My understanding about the word 'also' is that it's a conjuctive adverb on a par with other adverbs like 'in addition' and 'additionally' and it serves to modify the whole verb phrase rather than an individual verb. Consequently, my judgement is that the construction ''also seems to have.'' is truly grammatically correct as opposed to ''seems also to have.'' To me, ''also seems to have'', in relation to your above sentence, means in addition to previously mentioned problems, the subject has this another problem. The meaning can't be evoked by ''seems also to have'', which I can't even explain its intended sense. My answer might be off considering that I'm but a beginning grammar studier; I suppose Carillo would conclusively solve the matter when he comes.
