That’s like asking: I have that boat, it tends to rock a bit, whatcha recommend?
The answer could be ‘airplane carrier’ or ‘supertanker’ but maybe you would feel more at ease with a catamaran or stick with your current boat but sail on a lake instead of the open ocean.

Alkylpolyglucosides (part of the Montanovs) have a large space where they form liquid crystal structures (aka alpha gels) on the aqueous phase-oil phase-emulsifier triangular landscape called pseudoternary phase diagram. See random example
HERE page 8, other landscapes look very different and my not contain all possible phases and mixed-type areas or such of complete emulsion failure.
You can see that even minor changes of either of the three partners or their constituents might push you out of that area, possibly in one where the APGs do what they do second-best: foaming. Understanding emulsion types and your specific emulsion and its parts helps to guide you over that landscape to your target point. How you do that is impossible to predict just by looking at the products composition. However, with some well planned trials you could predict which adjustments are more or less likely to help.
Three strategies I see (on aformentioned page, you’re most likely somewhere on the left side but aim for a lamellar pattern): Use less emulsifier, add low polarity oils at sufficient amounts, and/or add more liquid crystal promoters (by preference of the monoglyceride or sorbitan ester type -> if you’re still in the HLB age = a low HLB co-emulsifier).
