Can you provide a more minimal example?
The following table works correctly here (maint and master):
| mean1 | mean2 |
|-------+-------|
| 08:00 | 08:00 |
| 09:00 | 09:00 |
| 00:00 | |
|-------+-------|
| 05:40 | 08:30 |
#+TBLFM: @5$1=vmean(@2..@-1);U
#+TBLFM: @5$2=vmean(@2..@-1);U
So I suspect this is something wrong with your first formula:
> #+TBLFM: $5=if(typeof($3-$2)==12, string(""), $3-$2);E
Let me know if you manage to nail down something more precise.
Thanks,
