In this instance it is likely you are not removing the yeast soon enough in the process.

After primary fermentation is complete you should leave it no longer than 2 days before harvesting your yeast. Dumping your yeast regularly will also help with this.

If you have some C02 you could attach the tube to the bottom of the dual valve and try and push some inside to dislodge the hops but ensure you don't go over 1.5 psi. But if you're bottling or kegging soon we would just suggest leaving it and when ready to transfer syphon out the top of the unit.
