Problem with item holograms

[Hakuyamu]

Hey guys,

I have an issue with items in holograms where they won't be displayed sometimes and some won't appear at all (the shulker box and the sun flower). Server version 1.15.2, Skript: latest stable version. This is my Code:

on click on player head:
    if {crate.isopening.%player%} is true:
        if {crate.hasopened.%player%} is not 4:
            if {crate.headopened.%clicked block%} is not set:
                add 1 to {crate.hasopened.%player%}
                set {crate.reward.%player%.%{crate.hasopened.%player%}%} to random integer between 1 and 4
                message "%{crate.reward.%player%.%{crate.hasopened.%player%}%}%"
                if {crate.reward.%player%.%{crate.hasopened.%player%}%} is 1:
                    wait 2 ticks
                    create holo object "&b&lStarter Spitzhacke;ItemStack:diamond_pickaxe;" with id "cratehead.%{crate.hasopened.%player%}%" at block 1 above clicked block
                if {crate.reward.%player%.%{crate.hasopened.%player%}%} is 2:
                    wait 2 ticks
                    create holo object "&6&l1.000 &e&lDollar;ItemStack:sunflower;" with id "cratehead.%{crate.hasopened.%player%}%" at block 1 above clicked block
                if {crate.reward.%player%.%{crate.hasopened.%player%}%} is 3:
                    wait 2 ticks
                    create holo object "&d&lShulker Box;ItemStack:shulker_box;" with id "cratehead.%{crate.hasopened.%player%}%" at block 1 above clicked block
                if {crate.reward.%player%.%{crate.hasopened.%player%}%} is 4:
                    wait 2 ticks
                    create holo object "&2&l8 &a&lSSmaragdblock;ItemStack:emerald_block;" with id "cratehead.%{crate.hasopened.%player%}%" at block 1 above clicked block
                set {crate.headopened.%clicked block%} to true
            else:
                message "&8» &cDieser Gewinn wurde bereits entlüftet!"
        if {crate.hasopened.%player%} is 4:
            loop all blocks in radius 5 of {crate.clickedec.%player%}:
                if y coord of loop-block is y coord of {crate.clickedec.%player%}:
                    if loop-block is player head:
                        set block under loop-block to {@cratemat}
                        delete {crate.headopened.%loop-block%}
            wait 2 seconds
            delete holo object "cratehead.1"
            delete holo object "cratehead.2"
            delete holo object "cratehead.3"
            delete holo object "cratehead.4"
            delete {crate.isopening.%player%}
            delete {crate.beingopen.%{crate.clickedec.%player%}%}
            set {crate.hasopened.%player%} to 0

I thank you in advance!
