Segregation at ER

I can’t understand why we had to lose so many seats in the South stand to allow for segregation of home and away fans for the cup game. Most clubs these days have H & A fans stood next to each other with a few stewards or they take out maybe 3 columns of seats and cover them with netting. We lost two blocks, one each in the upper and lower South stand. I could understand if it was a high risk game but Harrogate Town!! I heard an amusing chant just before KO. “You’re just a town full of tea rooms”, which made me and several others nearby have a good laugh.
Also, what is it with block FA7 in the South West corner, they never seem to sell seats in there. Why don’t they move the flag that covers half the block and cash in?
