Yes, so try making them shorter, 1.5" tall if you can. Washing and affinage takes some practice. How hard you should wash and how moist should you leave it after a wash -these are just a matter of practicing this.
I am sorry if I confused you - NO, this is a mesophilic type cheese. You add one type of thermophilic to stabilize it (giving it longer shelf like once it is fully aged).
Your cultures are a bit off for this cheese. The starter looks like some version of Flora Danica and I think it is too "buttery" for this cheese. Choose something more traditional such as Danisco Choozit MM100 as a mesophilic.
For the thermophilic - it looks like you are using a mystery culture that is a version of Thermo C or something of that sort - it's way too many thermophilics in this mixture. This isn't a thermophilic cheese. You are only suppose to add a little thermophilic to your mesophilic for stability and texture. Use TA50 or TA60 for that.
The B. Linens you are using - they may be OK but there is no way of knowing what it is and how strong it is.
My suggestion will be to buy name brand cultures that you know exactly what they are, what's in them, how they were made and packed and what's their expiration date. The re-packed products (such as the items you get at cheesemaking.com and the Hjemme Produktion) and off-brands like 'Goat Nutrition Limited' - I just can't attest to the type of strain, the strength, packing conditions, quality and production standards.
Danisco Choozit, Abiasa Rosell and CHR-Hansen are very popular brands because they are easy to work with, standarized to have the right strength and have very high quality. They are also well documented.
Also, when you buy from these known brands you have a great selection of different cultures for each type, so you can decide how red or stinky your B.Linen should be, how fast and high your PC would be, how blue or green your P.Roqueforti would be and how buttery, nutty, sharp or how much eye formation will your cheese have - by choosing the right starter culture.
