Replacement drop line coax cable quality,,wrong type of cable used

The old drop line a direct buried RG6 dual shield coax cable was replaced after 10+ years with a new cable inside an off orange colored conduit with the PPC label on it. The coax inside has the labeling that according to PPC product listing is for inside home use. I know a third party contractor did the install, but why would he not use the correct type of coax cable ( that is the outdoor flooded version) ?, the service here is working, however there is times of the day when there are high error readings on the modems event log. The conduit nearest the ground block is quite loose, I was thinking it should be a continuous piece from pedestal to ground block, a small portion does need to go under a concrete walkway block, then just buried in the ground to the pedestal inside. I,m not griping about the service, just the way it was done. The installer left several feet of new conduit with PPC flooded direct bury cable inside,,,,wondering why this was in the trash can ?.
