Carraige return problem in shopify

Hello,

The content of my metafield is in 3 lines : https://zigzagbe.tinytake.com/msc/NjU0ODkxNV8xOTA0ODE4MQ

Display on product page comes in 1 line : https://zigzagbe.tinytake.com/msc/NjU0ODkyMF8xOTA0ODE4Nw

I need in 3 lines !
Can you help ?


Theres is one difficulty :
Some contents will be in HTML, other text only.
When HTML, display should be fine as well ...


Thanks,
