Pinyin doesn't seem to align with hanzi when coming with erhua

[lturing]

firstly, thinks for your great work.
just like the title says, for example:
001464|sil wo3 dou1 hui4 shuo1 er2 hua4 yin1 le5 sp1 zher4 ne5 sp1 mingr2 jian4 sp1 hai2 bu2 cuo4 ba5 sil
001464|sil 我 都 会 说 儿 化 音 了 sp1 这 儿 sp1 呢 明 sp1 儿 见 还 不 sil

zip:
[('sil', 'sil'), ('我', 'wo3'), ('都', 'dou1'), ('会', 'hui4'), ('说', 'shuo1'), ('儿', 'er2'), ('化', 'hua4'), ('音', 'yin1'), ('了', 'le5'), ('sp1', 'sp1'), ('这', 'zher4'), ('儿', 'ne5'), ('sp1', 'sp1'), ('呢', 'mingr2'), ('明', 'jian4'), ('sp1', 'sp1'), ('儿', 'hai2'), ('见', 'bu2'), ('还', 'cuo4'), ('不', 'ba5'), ('sil', 'sil')]

'zher4' should respect to '这儿' , and there misses some hanzi in the tail.
do you think it matters?
