"Complete other task on administrative issues"写得对吗?

Responsible other administrative affairs

Complete不是负责而是完成的意思,另外other后面直接说负责什么，无须加task on sth（应该是task of sth）。最后，事务用affairs表达更好。

错了
issue一般指问题，争议，非事物
语句即顺序都不对

可以写成 take charge of other administrative affairs.
或
（I am）Be in charge of other administrative affairs.

确切点应该是：
Be responsible for other administrative affairs
