Got the same problem type of problem on EX5440 and QFX5100.
There are (very) slow limit on label stacking due to the chip.

Quoting the doc (Read 
https://www.juniper.net/documentation/en_US/junos/topics/reference/general/mpls-limitations-qfx-series.html) 
:

- Push of a maximum of three labels is supported in the MPLS edge switch 
if label swap is not done.

- Push of a maximum of two labels is supported in the MPLS edge switch 
if label swap is done.
