Time to switch investments? - Vanguard

Vet

Hello all!
Currently i'm investing with Vanguard in a variety of funds:
LS 100 - 22%
LS 80 - 51%
Retirement fund 2050 and 2055 - 6% and 2%
Emerging markets - 5%
All world High dividend Yield -  12%

After reading more into what each of the LS and Retirement funds offer, I feel the emerging markets and LS 100 may not be benefitting me much from having them.
 
My question is -
Should I switch the Emerging markets and LS100 into the LS80 or one of the retirement funds? Given the fact both units are down from January this year. 
OR
Should I just continue to invest in emerging markets to give more exposure to the global market when compared to the heavy US/UK weighting of the LS funds?

I'm 26 years old so I am hopefully planning to invest for the next 30+ years. I currently invest around £1150 per month. The Value of the S&S ISA is around £10.1k

That is a most bizarre allocation. What was your reasoning for doing that in the first place?  

You could just hold one fund for similar effect.

Initially started with LS 80. Since its for a long term investment I wanted more risk, hence LS 100. 
I then read into how the retirement funds would automatically reduce the risk as you're heading towards retirement age hence those 2 funds.
Emerging markets was to increase exposure to non-UK/US stocks. 
Dividend fund for future income stream.
