Encounter does not switch SDC between setup and hold STA

Hello, I'm designing a digital block with Encounter v14.26-s039_1. One input clock is a multiphase clock, programmable, coming from a custom analog block. In my MMMC view, I wrote two different .sdc files, one (called SS) to be used for the setup analysis (where I defined the multiphase clock with the first phase), the other (called FF) for the hold analysis  (multiphase clock defined with the last phase).

The problem is that when I run the timing analysis, Encounter considers ONLY the SS for both the setup and hold analysis. I don't know why it doesn't switch the sdc. Can you please help me to make it change the sdc to be considered for each analysis?

My mmmc.view file that I load with Import Design is the following:

And, my commands for the timing analysis are:

set_analysis_view -setup {setup_125c_NOuncert} -hold {hold_m55c_NOuncert}

timeDesign -preCTS -idealClock -pathReports -drvReports -slackReports -numPaths 50 -prefix data_gen_preCTS -outDir timingReports
report_timing -machine_readable -max_points 10000 -max_slack 0.75 -path_exceptions all > ./myreports/trialroute.rpt

timeDesign -preCTS -hold -expandedViews
report_timing -machine_readable -max_points 10000 -max_slack 0.75 -path_exceptions all -early > ./myreports/trialroute_hold.rpt

If then I go to  Timing->Debug Timing... I can see that only the file  ./sdc_encounterSS.sdc has been used for both setup and hold analysis.

Thanks a lot for any feedback
